• Molar mass of Na2SiO3: 122.06323856 g/mol (0.12206 kg/mol)

Calculation of the relative molecular and molar mass of Na2SiO3

• Mr[Na2SiO3] = Ar[Na] * 2 + Ar[O] * 3 + Ar[Si] = 22.98976928 * 2 + 15.9994 * 3 + 28.0855 = 122.06323856
• Molar mass (kg/mol) = Mr[Na2SiO3] : 1000 = 122.06323856 : 1000 = 0.12206 kg/mol
