Calculate the mass, in grams, of the solvent present in a 32.2% solution that contains 14.7 g of NaBr.

32g

Explanation:

We have to remember that for percent (w/w) concentration we usually write;

Percent concentration = mass of solute/mass of solution * 100

Since mass of solute = 14.7 g and percent concentration = 32.2%

Then

Mass of solution = mass of solute * 100 / percent concentration

Mass of solution = 14.7 * 100/32.2

Mass of solution = 46.7 g

Since mass of solution = mass of solute + mass of solvent

Mass of solute = 14.7 g

Mass of solution = 46.7g

Mass of solvent = 46.7g - 14.7g = 32g
