Molar and molecular weight of NaO2

• Relative molecular weight of NaO2: 54.98856928
• Molar mass of NaO2: 54.98856928 g/mol (0.05499 kg/mol)

Calculation of the relative molecular and molar mass of NaO2

• Mr[NaO2] = Ar[Na] + Ar[O] * 2 = 22.98976928 + 15.9994 * 2 = 54.98856928
• Molar mass (kg/mol) = Mr[NaO2] : 1000 = 54.98856928 : 1000 = 0.05499 kg/mol

NaO2: percent composition by element

• Sodium (Na) = 22.98976928 : 54.98856928 * 100 = 41.808 %
• Oxygen (O) = 31.9988 : 54.98856928 * 100 = 58.192 %
