A) Remember that molality (m) = moles of solute / kg solvent. So, using your data from Table 1, calculate the moles of each solute (glycerol, NaCl, and CaCl2) used in this lab by using the experimental molality and the mass (in kg) of water in each trial.. You must show all work to receive credit. B) Recall that the molar mass of a substance is expressed in g/mol. If we have a mass of a substance, and we know...

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
