WebTo determine the molar mass, we simply add the atomic masses of the atoms in the molecular formula but express the total in grams per mole, not atomic mass units. The masses of the atoms can be taken from the periodic table. 6 C = 6 × 12.011 = 72.066: 12 H = 12 × 1.0079 = 12.0948: 6 O = 6 × 15.999 WebQuestion: Calculate the mole fraction of LiCl in a 18.0% (by mass) aqueous solution.
