Molar and molecular weight of MnS

• Relative molecular weight of MnS: 87.003045
• Molar mass of MnS: 87.003045 g/mol (0.087 kg/mol)

Calculation of the relative molecular and molar mass of MnS

• Mr[MnS] = Ar[Mn] + Ar[S] = 54.938045 + 32.065 = 87.003045
• Molar mass (kg/mol) = Mr[MnS] : 1000 = 87.003045 : 1000 = 0.087 kg/mol

MnS: percent composition by element

• Manganese (Mn) = 54.938045 : 87.003045 * 100 = 63.145 %
• Sulfur (S) = 32.065 : 87.003045 * 100 = 36.855 %
