Titration of the solution with 0.224 M NaOH(aq) required 50.2 mL to reach the stoichiometric point. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. The mass (in grams) of a compound is equal to its molarity (in moles) multiply its molar mass: grams = mole × molar mass. 106.0 g/mol. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. Now that we know the molar mass of NaCl, we can find how many grams are in 2.5 moles of NaCl.
