A solution of salt and water is 33.0% salt by mass and has a density of 1.50 g/ml. what mass of the salt in grams is in 5.00l of this solution?

To answer this item, we solve first for the mass of the solution by multiplying the density by the volume. That is,

m = (density) (volume)

Substituting the known values,

m = (1.50 g/mL) (5L) (1000 mL/1L)

m = 7500 grams

To determine the mass of the salt in the solution, multiply the calculated mass of the solution by the decimal equivalent of the percent salt in the solution.

m of salt = (7500 g) (0.33)

m of salt = 2475 grams

Answer: 2475 grams
