Let’s calculate the mass of salt that remains after evaporation of 400 g of a 68% solution.

W (in-va) = m (in-va) / m (solution) • 100%.

m (in-va) = W (in-va) • m (solution) / 100% = 68 • 400/100% = 272 g.

The water in the solution will have a mass.

m (water) = m (solution) – m (in-va) = 400 – 272 = 128 g.
