Molar and molecular weight of Li2SiO3

• Molecular formula: Li2SiO3 or Li2O3Si
• Relative molecular weight of Li2SiO3: 89.9657
• Molar mass of Li2SiO3: 89.9657 g/mol (0.08997 kg/mol)

Calculation of the relative molecular and molar mass of Li2SiO3

• Mr[Li2SiO3] = Ar[Li] * 2 + Ar[O] * 3 + Ar[Si] = 6.941 * 2 + 15.9994 * 3 + 28.0855 = 89.9657
• Molar mass (kg/mol) = Mr[Li2SiO3] : 1000 = 89.9657 : 1000 = 0.08997 kg/mol

Li2SiO3: percent composition by element

• Lithium (Li) = 13.882 : 89.9657 * 100 = 15.43 %
