Molar and molecular weight of Li2SO4

• Molecular formula: Li2SO4 or Li2O4S
• Relative molecular weight of Li2SO4: 109.9446
• Molar mass of Li2SO4: 109.9446 g/mol (0.10994 kg/mol)

Calculation of the relative molecular and molar mass of Li2SO4

• Mr[Li2SO4] = Ar[Li] * 2 + Ar[O] * 4 + Ar[S] = 6.941 * 2 + 15.9994 * 4 + 32.065 = 109.9446
• Molar mass (kg/mol) = Mr[Li2SO4] : 1000 = 109.9446 : 1000 = 0.10994 kg/mol

Li2SO4: percent composition by element

• Lithium (Li) = 13.882 : 109.9446 * 100 = 12.626 %
• Oxygen (O) = 63.9976 : 109.9446 * 100 = 58.209 %
• Sulfur (S) = 32.065 : 109.9446 * 100 = 29.165 %
