Molar and molecular weight of NaHCO3

• Molecular formula: NaHCO3 or CHNaO3
• Relative molecular weight of NaHCO3: 84.00660928
• Molar mass of NaHCO3: 84.00660928 g/mol (0.08401 kg/mol)

Calculation of the relative molecular and molar mass of NaHCO3

• Mr[NaHCO3] = Ar[C] + Ar[H] + Ar[Na] + Ar[O] * 3 = 12.0107 + 1.00794 + 22.98976928 + 15.9994 * 3 = 84.00660928
• Molar mass (kg/mol) = Mr[NaHCO3] : 1000 = 84.00660928 : 1000 = 0.08401 kg/mol

NaHCO3: percent composition by element

• Carbon (C) = 12.0107 : 84.00660928 * 100 = 14.297 %
• Hydrogen (H) = 1.00794 : 84.00660928 * 100 = 1.2 %
• Sodium (Na) = 22.98976928 : 84.00660928 * 100 = 27.367 %
• Oxygen (O) = 47.9982 : 84.00660928 * 100 = 57.136 %
