If 17.5 g of NaCl is dissolved in 100. g of water, what is the mass...

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
