Molar and molecular weight of INa

• Molecular formula: INa or NaI
• Relative molecular weight of INa: 149.89423928
• Molar mass of INa: 149.89423928 g/mol (0.14989 kg/mol)

Calculation of the relative molecular and molar mass of INa

• Mr[INa] = Ar[I] + Ar[Na] = 126.90447 + 22.98976928 = 149.89423928
• Molar mass (kg/mol) = Mr[INa] : 1000 = 149.89423928 : 1000 = 0.14989 kg/mol

INa: percent composition by element

• Iodine (I) = 126.90447 : 149.89423928 * 100 = 84.663 %
• Sodium (Na) = 22.98976928 : 149.89423928 * 100 = 15.337 %
