Molar and molecular weight of MnSO4

• Molecular formula: MnSO4 or MnO4S
• Relative molecular weight of MnSO4: 151.000645
• Molar mass of MnSO4: 151.000645 g/mol (0.151 kg/mol)

Calculation of the relative molecular and molar mass of MnSO4

• Mr[MnSO4] = Ar[Mn] + Ar[O] * 4 + Ar[S] = 54.938045 + 15.9994 * 4 + 32.065 = 151.000645
• Molar mass (kg/mol) = Mr[MnSO4] : 1000 = 151.000645 : 1000 = 0.151 kg/mol

MnSO4: percent composition by element

• Manganese (Mn) = 54.938045 : 151.000645 * 100 = 36.383 %
• Oxygen (O) = 63.9976 : 151.000645 * 100 = 42.382 %
• Sulfur (S) = 32.065 : 151.000645 * 100 = 21.235 %
