Molar and molecular weight of Li2O3Si

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

Calculation of the relative molecular and molar mass of Li2O3Si

• Mr[Li2O3Si] = Ar[Li] * 2 + Ar[O] * 3 + Ar[Si] = 6.941 * 2 + 15.9994 * 3 + 28.0855 = 89.9657
• Molar mass (kg/mol) = Mr[Li2O3Si] : 1000 = 89.9657 : 1000 = 0.08997 kg/mol

Li2O3Si: percent composition by element

• Lithium (Li) = 13.882 : 89.9657 * 100 = 15.43 %
• Oxygen (O) = 47.9982 : 89.9657 * 100 = 53.352 %
• Silicon (Si) = 28.0855 : 89.9657 * 100 = 31.218 %
