Question

What is the molar mass of calcium chloride (`CaCl_2`)?

Answer 1

110.98 g.

Explanation:

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.
