If 17.5 g of NaCl is dissolved in 100. g of water, what is the mass % concentration of NaCl in this solution?

Note:

1. Use 3 sig figs for your final answer.

2. Do not answer as fractions. For example, if you think 30% is the correct answer, either "30" or "30%" will be accepted, but "0.30" will not. "30%" will actually be converted to 30 automatically

Solutions

Expert Solution

mass % concentration of NaCl = (mass of NaCl / mass of solute + mass of solvent) X 100

= 17.5/(17.5 + 100) X 100

= 14.9

= 15%
