Molar and molecular weight of NaAlO2

• Molecular formula: NaAlO2 or AlNaO2
• Relative molecular weight of NaAlO2: 81.97010788
• Molar mass of NaAlO2: 81.97010788 g/mol (0.08197 kg/mol)

Calculation of the relative molecular and molar mass of NaAlO2

• Mr[NaAlO2] = Ar[Al] + Ar[Na] + Ar[O] * 2 = 26.9815386 + 22.98976928 + 15.9994 * 2 = 81.97010788
• Molar mass (kg/mol) = Mr[NaAlO2] : 1000 = 81.97010788 : 1000 = 0.08197 kg/mol

NaAlO2: percent composition by element

• Aluminum (Al) = 26.9815386 : 81.97010788 * 100 = 32.916 %
• Sodium (Na) = 22.98976928 : 81.97010788 * 100 = 28.047 %
• Oxygen (O) = 31.9988 : 81.97010788 * 100 = 39.037 %
