Molar and molecular weight of Li2SeO4

• Relative molecular weight of Li2SeO4: 156.8396
• Molar mass of Li2SeO4: 156.8396 g/mol (0.15684 kg/mol)

Calculation of the relative molecular and molar mass of Li2SeO4

• Mr[Li2SeO4] = Ar[Li] * 2 + Ar[Se] + Ar[O] * 4 = 6.941 * 2 + 78.96 + 15.9994 * 4 = 156.8396
• Molar mass (kg/mol) = Mr[Li2SeO4] : 1000 = 156.8396 : 1000 = 0.15684 kg/mol

Li2SeO4: percent composition by element

• Lithium (Li) = 13.882 : 156.8396 * 100 = 8.851 %
• Selenium (Se) = 78.96 : 156.8396 * 100 = 50.344 %
• Oxygen (O) = 63.9976 : 156.8396 * 100 = 40.804 %
