| **In 200 g of water was dissolved 50 g of sodium chloride. Calculate the mass fraction of sodium chloride in the resulting solution.**

Find the mass of the resulting solution after dissolving sodium chloride in water.

m (solution) = m (H2O) + m (NaCl) = 200 g + 50 g = 250 g.

The mass fraction of sodium chloride in the resulting solution is.

W (NaCl) = m (NaCl) / m (solution) • 100% = 50 g / 250 g • 100% = 20%.
