Molar and molecular weight of Na2CrO4

• Molecular formula: Na2CrO4 or CrNa2O4
• Relative molecular weight of Na2CrO4: 161.97323856
• Molar mass of Na2CrO4: 161.97323856 g/mol (0.16197 kg/mol)

Calculation of the relative molecular and molar mass of Na2CrO4

• Mr[Na2CrO4] = Ar[Cr] + Ar[Na] * 2 + Ar[O] * 4 = 51.9961 + 22.98976928 * 2 + 15.9994 * 4 = 161.97323856
• Molar mass (kg/mol) = Mr[Na2CrO4] : 1000 = 161.97323856 : 1000 = 0.16197 kg/mol
