The mass fraction is the ratio of the mass of the solute to the mass of the entire solution.
The mass fraction of a solute is calculated as a percentage or in unit fractions.
Let’s find the mass fraction of salt in the solution by the formula:
w (solution) = m (salt) * 100% / m (solution) = 40 g * 100% / 800 g = 5%.
