Can 1750 mL of water dissolve 4.6 moles of Copper Sulfate CuSO4? _________ Why? / Why not?
Answer:
No, you cannot dissolve 4.6 moles of copper sulfate, CuSO₄, in 1750mL of water.Explanation:
This question is part of a Post-Lab exercise sheet.
Such sheet include the saturation concentrations for several salts.
The saturation concentration of Copper Sulfate, CuSO₄, indicated in the table is 1.380M.
That means that 1.380 moles of copper sulfate is the maximum amount that can be dissolved in one liter of solution.
Find the molar concentration for 4.6 moles of copper sulfate in 1,750 mL of water.
You need to assume that the volume of water (1750mL) is the volume of the solution. This is, that the 4.6 moles of copper sulfate have a negligible volume.
1. Volume in liters:
V = 1,750 mL × 1 liter / 1,000 mL = 1.75 liter2. Molar concentration, molarity, M:
M = number of moles of solute / volume of solution in litersM = 4.6 moles / 1.75 liter = 2.6 MSince the solution is saturated at 1.380M, you cannot reach the 2.6M concentration, meaning that you cannot dissolve 4.6 moles of copper sulfate, CuSO₄ in 1750mL of water.
Adding solute to the saturated solution. will leave solids at the bottom of the container, without changing the concentration of the solution.
4.6 moles of Copper Sulfate cannot be dissolved in 1,750 mL of water. The reason why is because 4.6 moles of more than the 2.263 moles of Copper Sulfate that can be dissolved in 1,750 mL of water.Reasons:
The maximum solubility of copper sulfate, CuSO₄ in water at 20°C is 20.7 grams in 100 g of water;
Density of water, ρ = 997 kg/m³
[tex]\displaystyle \ The \ volume \ 100 \ g \ of \ water = \frac{0.1 \, kg}{997 \, kg/m^3} \approx 1.003 \times 10^{-4} \ m^3 = 100.3 \, ml[/tex]
The number of moles, n, of CuSO₄ in 20.7 grams is given as follows;
[tex]\displaystyle n = \frac{20.7 \, g}{159.609 \, g/mol} \approx 0.1296919 \, moles[/tex]
0.1296919 moles can be dissolved in 100.3 mL of water
Therefore;
[tex]1750 \, mL \ of \ water \ an \ dissolve\ \displaystyle \frac{0.1296919 \ moles}{100.3 \, mL} \times 1750 \, mL \approx 2.263 \ moles[/tex]
The maximum amount of copper sulfate that can be dissolved in 1,750 mL of water at 20°C is 2.263 moles.
Therefore;
1,750 mL of water cannot dissolve up to 4.6 moles of Copper Sulfate CuSO₄ at 20°This is so because the solubility of copper sulfate in 1750 mL of water is approximately 2.263 moles, which is less than the given 4.6 moles.

An ecosystem is the specific environment in which an organism lives and includes the living and non-living components that organisms interact with. It's a site of competition for limited resources, influenced by numerous environmental variables, ultimately determining which organisms can exist within that ecosystem.
Explanation:The specific environment in which an organism lives is also referred to as its ecosystem. An ecosystem is a community of living organisms interacting with each other and their non-living (abiotic) environment. This can be as small as a tide pool or as vast as the Amazon Rainforest. These ecosystems are often sites of competition for limited resources, which include organic material, sunlight, and mineral nutrients. These resources are vital for an organism's survival and growth.
Competition arises both within species (intraspecific competition) and among different species (interspecific competition). This competition is driven by the theory of natural selection, where those organisms best adapted to their environment are more likely to survive and reproduce.
Other factors affecting an organism's life within an ecosystem include the ecosystem's physical and geographic environment, such as latitude, rainfall, topography, and available species. All these collectively decide which organisms can exist within a particular habitat.

How many moles of each element are in 1 mole of ammonium nitrate?
This is the formula for ammonium nitrate NH4NO3
Answer:
Of moles of NH4NO3 = 16/80 i.e. 0.2 moles of Ammonium Nitrate. 1 molecule of NH4NO3 contains 1 atom of N. Hence, 1 mole of NH4NO3 would contain 1 mole of Nitrogen atoms and therefore 0.2 moles of NH4NO3 should contain 0.2 moles of Nitrogen atoms.Explanation:
In 1 mole of ammonium nitrate (NH4₄NO₃), there are 2 moles of nitrogen, 4 moles of hydrogen, and 3 moles of oxygen.
The chemically correct formula for ammonium nitrate is NH4₄NO₃. When determining how many moles of each element are in 1 mole of ammonium nitrate, it is important to analyze the formula. Each molecule contains one nitrogen atom from the ammonium ion (NH4₄⁺) and one nitrogen atom from the nitrate ion (NO₃⁻), totaling two moles of nitrogen (N).
Additionally, there are four hydrogen atoms from the ammonium ion and no hydrogen from the nitrate ion, giving us four moles of hydrogen (H). Finally, the nitrate ion contains three oxygen atoms, thus there are three moles of oxygen (O). Therefore, 1 mole of ammonium nitrate consists of 2 moles of nitrogen, 4 moles of hydrogen, and 3 moles of oxygen.
Prepare a 0.50 L of a 1.0 M solution of potassium sulfate. Determine the amount of potassium sulfate needed in correct significant figures.
A) 68 g
B) 87 g
C) 270 g
D) 349 g
I can't figure out the answer.
Answer:
B) 87g
Explanation:
Usatestprep said it
Final answer:
To prepare 0.50 L of a 1.0 M solution of potassium sulfate, 87 g of the solute is needed. So the correct option is B.
Explanation:
To prepare a 0.50 L of a 1.0 M solution of potassium sulfate (K₂SO₄), first, we need to calculate the number of moles of the solute needed using the molarity equation, M = moles/L. For a 1.0 M solution, we need 1.0 mole of K₂SO₄ per liter. However, since we're preparing only 0.50 L, we need 0.50 moles of K₂SO₄.
Molar mass of K2SO4 = 2(K) + S + 4(O) = 2(39.10) + 32.07 + 4(16.00) = 174.27 g/mol.
Mass of K2SO4 needed = moles × molar mass = 0.50 moles × 174.27 g/mol = 87.135 g.
Using the correct significant figures, the mass of the solute needed is 87 g, which corresponds to option B.

Which of the following individual actions would do the
most to reduce atmospheric methane?
The top individual action to curb atmospheric methane is reducing consumption of meat and dairy, as these industries are primary contributors to methane production. Also, minimising waste production can help, as waste decomposition in landfills generates considerable methane.
Explanation:The most effective individual action to reduce atmospheric methane is to reduce consumption of meat and dairy products. Methane is produced by digestive processes in ruminant livestock, such as cows, sheep, and goats. These animals are typically raised for meat and dairy production, so by reducing our intake, we can help decrease the number of these animals, and thus decrease the amount of methane produced. This also has the effect of reducing the amount of grain required for livestock feed, since less livestock would be raised. This grain could then be used more efficiently to feed humans directly. Additionally, reducing waste production can also help mitigate methane production, because waste decomposition in landfills is another major source of atmospheric methane.

Reducing livestock agriculture, implementing sustainable grazing practices, and feeding livestock supplements to lower methane production are key actions for reducing atmospheric methane. Additionally, transitioning to clean energy and planting trees can contribute to lowering greenhouse gas concentrations.
Explanation:To reduce atmospheric methane, the most effective individual action would be decreasing livestock agriculture. Livestock, particularly ruminants like cows and goats, have microbiomes that produce methane during digestion. Additionally, implementing sustainable grazing practices and improving pasture management can mitigate carbon sequestration and offset methane emissions. Feed supplement programs that reduce methane production in livestock can also have significant impacts in reducing this potent greenhouse gas emission.
Another approach is to reduce activities that create anaerobic conditions conducive to methanogen growth, such as rice cultivation in flooded fields. Switching to clean energy sources like wind, solar, and hydropower, which do not emit methane, is also an effective strategy to combat global warming. Lastly, planting more trees can help absorb carbon dioxide, another greenhouse gas that works in tandem with methane to increase global temperatures.

193.38 K was the initial temperature of the krypton.
Explanation:
Data given:
Initial volume of the krypton gas = 6 litres
initial pressure of the krypton gas = 0.960 atm
initial temperature of the krypton gas = ?
final volume of the krypton gas = 7.70 litres
final pressure of the Krypton gas = 1.25 atm
final temperature of the krypton gas = 55 degrees or 273.25+55 = 323.15 K
Applying the Combined Gas Laws:
[tex]\frac{P1V1}{T1} = \frac{P2V2}{T2}[/tex]
Rearranging the equation:
T1 = [tex]\frac{P1V1T2}{P2V2}[/tex]

Answer:
516.8 K or 243.8 C
Explanation:
- First figure out which gas law to use. In this case we need to use Gay-Lussac's law. This is P1/T1 = P2/T2.
- Next, we need to rearrange this to fit our problem. We should do...
T2 = T1P2/P1
- Now, we need to find our variables. For example...
T1 = 323 K
P1 = 2.00 atm
P2 = 3.20 atm
Next, fill in these numbers to fit our equation. For example...
T2 = 323 x 3.20 / 2.00 = 516.8 K
