• Relative molecular weight of BeCl2: 79.918182
• Molar mass of BeCl2: 79.918182 g/mol (0.07992 kg/mol)

Calculation of the relative molecular and molar mass of BeCl2

• Mr[BeCl2] = Ar[Be] + Ar[Cl] * 2 = 9.012182 + 35.453 * 2 = 79.918182
• Molar mass (kg/mol) = Mr[BeCl2] : 1000 = 79.918182 : 1000 = 0.07992 kg/mol

BeCl2: percent composition by element

• Beryllium (Be) = 9.012182 : 79.918182 * 100 = 11.277 %
• Chlorine (Cl) = 70.906 : 79.918182 * 100 = 88.723 %
