The molar mass of CaCl2 is approximately 110.98 g/mol, which is the sum of the atomic masses of one calcium atom (40.08 g/mol) and two chlorine atoms (35.45 g/mol each).
To determine the percent of calcium chloride in CaCl2, we can use the following formula:
Percent of Calcium Chloride = (Mass of Calcium Chloride / Total Mass of Compound) × 100
In CaCl2, the mass of calcium chloride is 110.98 g/mol. Therefore, the percent of calcium chloride can be calculated as follows:
Percent of Calcium Chloride = (110.98 g/mol / 110.98 g/mol) × 100 = 100%
This means that calcium chloride (CaCl2) is 100% calcium chloride. It does not contain any other elements or compounds.
