Molar and molecular weight of Li2CrO4

• Molecular formula: Li2CrO4 or CrLi2O4
• Relative molecular weight of Li2CrO4: 129.8757
• Molar mass of Li2CrO4: 129.8757 g/mol (0.12988 kg/mol)

Calculation of the relative molecular and molar mass of Li2CrO4

• Mr[Li2CrO4] = Ar[Cr] + Ar[Li] * 2 + Ar[O] * 4 = 51.9961 + 6.941 * 2 + 15.9994 * 4 = 129.8757
• Molar mass (kg/mol) = Mr[Li2CrO4] : 1000 = 129.8757 : 1000 = 0.12988 kg/mol

Li2CrO4: percent composition by element
