Copper sulfate dissolves better in warm water because higher temperatures typically increase the solubility of solids. Warm water has more kinetic energy, allowing the copper sulfate particles to break apart more easily and mix with the water molecules.
The solubility of copper sulfate in water at 60 degrees Celsius is approximately 203 g/L. Therefore, in 50g of water, the maximum mass of copper sulfate that can dissolve would be 203g/L x 0.05 L = 10.15g.
The relative formula mass of copper sulfate is 159.61 g/mol. This is calculated by adding together the atomic masses of copper, sulfur, and oxygen in the compound.
Solid copper appears to gain mass when heated in air, because the copper reacts with oxygen in the air to form copper oxide. However, the actual mass of the copper does not increase; the mass of the solid increases by a value equal to the mass of oxygen removed from the air.
To find the number of moles of copper II sulfate Yonas has, you need to divide the given mass by the molar mass of the compound. The molar mass of copper II sulfate is 159.61 g/mol. 44.78 g / 159.61 g/mol = 0.281 moles of copper II sulfate.
Copper(II) sulfate can fom 3 hydrates; the molar mass increase from the anhydrous salt to heptahydrate.
When hydrated copper sulfate is heated, it loses water molecules and forms anhydrous copper sulfate, which has a lower mass due to the removal of water. So, the mass would decrease upon heating hydrated copper sulfate.
Hydrated copper sulfate, CuSO4ยท5H2O, contains 36.10% water by mass.
To find the mass of anhydrous salt, we need to find the molar mass of water in the copper-II sulfate pentahydrate (5 molecules of water per molecule of copper-II sulfate). The molar mass of water is 18 g/mol. Therefore, the mass of water in 2.3754g of copper-II sulfate pentahydrate is 5 * 18 = 90g. Subtracting this from the initial mass gives us the mass of anhydrous salt: 2.3754g - 90g = 1.3754g.
In general when you dissolve something in water the density of the solution will be greater than the density of the original water. This is because the solute (in this case, copper sulfate) will take up space between the water molecules, increasing the mass of the solution without increasing the volume. The density is calculated as mass divided by volume, so increasing the mass without increasing the volume will increase the density.
When water is added to copper sulfate, the copper sulfate dissolves in water to form a blue-colored solution. This is a physical change as the copper sulfate molecules remain unchanged, only dispersing evenly in the water.
Copper sulfate dissolves better in warm water because higher temperatures typically increase the solubility of solids. Warm water has more kinetic energy, allowing the copper sulfate particles to break apart more easily and mix with the water molecules.
To calculate this, you would need to consider the molar masses of copper(II) sulfate pentahydrate and anhydrous copper(II) sulfate. Copper(II) sulfate pentahydrate has a molar mass that includes water molecules, so you need to determine the molar mass difference between the two compounds. Using this information, you can calculate the amount of copper(II) sulfate pentahydrate needed to obtain 10.0 grams of anhydrous copper(II) sulfate.
The solubility of copper sulfate in water at 60 degrees Celsius is approximately 203 g/L. Therefore, in 50g of water, the maximum mass of copper sulfate that can dissolve would be 203g/L x 0.05 L = 10.15g.
To find the molar mass of copper (II) sulfate pentahydrate, calculate the individual molar masses of each element present (Cu, S, O, and H) from the periodic table, and then multiply by the respective subscript in the formula. Add up the molar masses of copper (II) sulfate (CuSOโ) and five water molecules (5HโO) to get the molar mass of copper (II) sulfate pentahydrate.
The relative formula mass of copper sulfate is 159.61 g/mol. This is calculated by adding together the atomic masses of copper, sulfur, and oxygen in the compound.
To calculate how much water is released in a sample of copper sulfate, you need to determine the difference in mass before and after heating the sample. Heat the sample to drive off the water, then weigh the sample again. The difference in mass is the amount of water released from the copper sulfate.
