| The mass of the solution after the complete dissolution of copper sulfate in water. Knowing that the density of water is 1.000, then the volume and mass will be equal.
m (solution) = m (CuSO4) + m (H2O) = 45 g + 450 g = 495 g.
Determine the mass fraction of salt in the resulting solution.
W (CuSO4) = m (CuSO4) / m (solution) • 100% = 45 g / 495 g • 100% = 9.09%.
