Answer is: dissolve 74,9 grams CuSO₄·5H₂O in one liter volumetric flask.

V (CuSO₄·5H₂O) = 1 L.

c (CuSO₄·5H₂O) = 0,30 mol/L.

n (CuSO₄·5H₂O) = V (CuSO₄·5H₂O) · c (CuSO₄·5H₂O).

n (CuSO₄·5H₂O) = 1 L · 0,3 mol/L.

n (CuSO₄·5H₂O) = 0,3 mol.

m (CuSO₄·5H₂O) = n (CuSO₄·5H₂O) · M (CuSO₄·5H₂O).

m (CuSO₄·5H₂O) = 0,3 mol · 249,7 g/mol.

m (CuSO₄·5H₂O) = 74,9 g.
