Molar and molecular weight of Li3PO4

• Molecular formula: Li3PO4 or Li3O4P
• Relative molecular weight of Li3PO4: 115.794362
• Molar mass of Li3PO4: 115.794362 g/mol (0.11579 kg/mol)

Calculation of the relative molecular and molar mass of Li3PO4

• Mr[Li3PO4] = Ar[Li] * 3 + Ar[O] * 4 + Ar[P] = 6.941 * 3 + 15.9994 * 4 + 30.973762 = 115.794362
• Molar mass (kg/mol) = Mr[Li3PO4] : 1000 = 115.794362 : 1000 = 0.11579 kg/mol

Li3PO4: percent composition by element

• Lithium (Li) = 20.823 : 115.794362 * 100 = 17.983 %
• Oxygen (O) = 63.9976 : 115.794362 * 100 = 55.268 %
• Phosphorus (P) = 30.973762 : 115.794362 * 100 = 26.749 %
