# What will be the mass fraction of copper sulfate in a solution of 187 g of water and 13 g of copper sulfate?

August 30, 2021 | education

| Water formula: H2O.

Copper sulfate formula: CuSO4.

1) Find the mass of the solution. To do this, add the mass of water with the mass of copper sulfate: 187 + 13 = 200g.

2) In this case, the mass of the solute will be equal to the mass of copper sulfate and equal to 13g.

3) Find the mass fraction of copper sulfate in the solution. For this, the mass of the solute is divided by the mass of the solution and multiplied by one hundred percent: 13/200 * 100 = 6.5% – the answer.
