Answer:

0.34 L

Explanation:

Step 1: Calculate the volume of 25 % m/v solution that contains 85 g of copper sulphate

The concentration of the solution is 25% m/v, that is, there are 25 g of copper sulphate (solute) every 100 mL of solution.

85 g CuSO₄ × 100 mL Solution/25 g CuSO₄ = 340 mL Solution

Step 2: Convert the volume of solution to Liters

We will use the conversion factor 1 L = 1000 mL.

340 mL × 1 L/1000 mL = 0.34 L
