Answer:

034 L of solution

Explanation:

% mass/volume is a sort of concentration that indicates mass of solute in 100 mL of solution.

In this case, we have 25 g of CuSO₄ in 100 mL of solution

We can make this rule of three to solve the answer:

25 g of solute is contained in 100 mL of solution

Our 85 g may be contained in (85 . 100) /25 = 340 mL

We convert volume from mL to L

340mL . 1L / 1000mL = 0.34 L
