The molar mass of CaCl_2 is 111.0 g/mole and the molar mass of water is 18.02 g/mol. Determine how many grams of CaCl2 must be dissolved to make 2.15 L of 0.05020 M Cl. What is the molar mass of Cl-?

2016年9月5日 · The molar mass of a compound is just the molar masses of every element in the compound added up. Since the molar mass of Calcium is 40.08 g and the molar mass of Chlorine is 35.45, it would be #40.08 g + 35.45 g + 35.45 g# (with 2 Chlorines according to the subscript.) That leaves you with 110.98 g.
