Molar and molecular weight of BeS

• Relative molecular weight of BeS: 41.077182
• Molar mass of BeS: 41.077182 g/mol (0.04108 kg/mol)

Calculation of the relative molecular and molar mass of BeS

• Mr[BeS] = Ar[Be] + Ar[S] = 9.012182 + 32.065 = 41.077182
• Molar mass (kg/mol) = Mr[BeS] : 1000 = 41.077182 : 1000 = 0.04108 kg/mol

BeS: percent composition by element

• Beryllium (Be) = 9.012182 : 41.077182 * 100 = 21.94 %
• Sulfur (S) = 32.065 : 41.077182 * 100 = 78.06 %
