Molar and molecular weight of Na2O

• Relative molecular weight of Na2O: 61.97893856
• Molar mass of Na2O: 61.97893856 g/mol (0.06198 kg/mol)

Calculation of the relative molecular and molar mass of Na2O

• Mr[Na2O] = Ar[Na] * 2 + Ar[O] = 22.98976928 * 2 + 15.9994 = 61.97893856
• Molar mass (kg/mol) = Mr[Na2O] : 1000 = 61.97893856 : 1000 = 0.06198 kg/mol

Na2O: percent composition by element

• Sodium (Na) = 45.97953856 : 61.97893856 * 100 = 74.186 %
• Oxygen (O) = 15.9994 : 61.97893856 * 100 = 25.814 %
