← Molecular and molar mass

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

Element	Total atoms	Atomic mass	Total mass
Li (Lithium)	2	6.941	13.882
Se (Selenium)	1	78.96	78.96
O (Oxygen)	4	15.9994	63.9976
			156.8396

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 %
