What is the fraction of the solute if 150 g of water and 50 g of salt were taken to prepare the solution?

The mass fraction of a solute is the ratio of the mass of the solute to the mass of the solution. Expressed by the formula:
w = m (solution in-va) / m (solution)
the mass of the solute (mass of the salt) is 50 g
mass of solution (equal to the sum of the mass of the solute and the mass of the solvent (water)) = 50 + 150 = 200 g
w = 50/200 = 0.25 (in fractions of a unit) or 25%
