Answer 1

Mass fraction of copper(II) sulfate in a saturated solution at 20 degrees Celsius

To determine whether the solution is dilute or concentrated, we need to calculate the mass fraction of copper(II) sulfate in the solution at 20 degrees Celsius.

Unfortunately, I couldn't find specific search results for the mass fraction of copper(II) sulfate in a saturated solution at 20 degrees Celsius. However, I can provide you with some general information on how to calculate the mass fraction.

The mass fraction of a solute in a solution is calculated by dividing the mass of the solute by the total mass of the solution and multiplying by 100.

Mass fraction (%) = (mass of solute / mass of solution) x 100

To calculate the mass fraction of copper(II) sulfate, you would need to know the masses of both the solute (copper(II) sulfate) and the solution.

If you have the masses of the solute and the solution, you can substitute those values into the formula to calculate the mass fraction.

Please provide the masses of the solute and the solution so that I can help you calculate the mass fraction of copper(II) sulfate in the saturated solution at 20 degrees Celsius.

Mass fraction of sodium chloride in a saturated solution at 100 degrees Celsius

Similarly, to determine whether the solution is dilute or concentrated, we need to calculate the mass fraction of sodium chloride in the solution at 100 degrees Celsius.
