Molar and molecular weight of CaCl2

• Relative molecular weight of CaCl2: 110.984
• Molar mass of CaCl2: 110.984 g/mol (0.11098 kg/mol)

Calculation of the relative molecular and molar mass of CaCl2

• Mr[CaCl2] = Ar[Ca] + Ar[Cl] * 2 = 40.078 + 35.453 * 2 = 110.984
• Molar mass (kg/mol) = Mr[CaCl2] : 1000 = 110.984 : 1000 = 0.11098 kg/mol

CaCl2: percent composition by element

• Calcium (Ca) = 40.078 : 110.984 * 100 = 36.112 %
• Chlorine (Cl) = 70.906 : 110.984 * 100 = 63.888 %
