Molar and molecular weight of MgSiO3

• Relative molecular weight of MgSiO3: 100.3887
• Molar mass of MgSiO3: 100.3887 g/mol (0.10039 kg/mol)

Calculation of the relative molecular and molar mass of MgSiO3

• Mr[MgSiO3] = Ar[Mg] + Ar[Si] + Ar[O] * 3 = 24.305 + 28.0855 + 15.9994 * 3 = 100.3887
• Molar mass (kg/mol) = Mr[MgSiO3] : 1000 = 100.3887 : 1000 = 0.10039 kg/mol

MgSiO3: percent composition by element

• Magnesium (Mg) = 24.305 : 100.3887 * 100 = 24.211 %
• Silicon (Si) = 28.0855 : 100.3887 * 100 = 27.977 %
• Oxygen (O) = 47.9982 : 100.3887 * 100 = 47.812 %
