What is the percent by mass of an 80.0 g solution of salt and water containing 25.0 g of salt?
Given: Mass of salt (solute) = 25.0 g, Mass of solution = 80.0 g Required: % by mass salt solution Equation: % by mass = (mass of salt/mass of solution) x 100 Solution: % by mass = (25.0 g/80.0 g) x 100 % by mass = (0.3125) x 100 Answer: % by mass = 31.25% by mass salt solution This means that the presence of 25 g salt in an 80 g salt solution has a concentration of 31.25 % by mass.
