Calculate the mass of a 6% sodium chloride solution weighing 30 g.

To determine the mass of a solution containing 30 g of sodium chloride, we will use the formula.
W (in-va) = m (in-va) / m (solution) • 100%.
m (solution) = m (in-va) / W (in-va) • 100%.
m (solution) = 30 g / 6% • 100% = 500 g.
The mass of water in solution.
m (H2O) = m (solution) – m (in-va) = 500 g – 30 g = 470 g.
