Molar and molecular weight of MgS

• Relative molecular weight of MgS: 56.37
• Molar mass of MgS: 56.37 g/mol (0.05637 kg/mol)

Calculation of the relative molecular and molar mass of MgS

• Mr[MgS] = Ar[Mg] + Ar[S] = 24.305 + 32.065 = 56.37
• Molar mass (kg/mol) = Mr[MgS] : 1000 = 56.37 : 1000 = 0.05637 kg/mol

MgS: percent composition by element

• Magnesium (Mg) = 24.305 : 56.37 * 100 = 43.117 %
• Sulfur (S) = 32.065 : 56.37 * 100 = 56.883 %
