The molar mass of bicarbonate (HCO₃) is calculated by adding the atomic masses of its constituent elements. The formula for bicarbonate is HCO₃, which consists of one hydrogen (H) atom, one carbon (C) atom, and three oxygen (O) atoms.
Here is the breakdown of the molar mass calculation:
- Hydrogen (H): 1.008 g/mol
- Carbon (C): 12.011 g/mol
- Oxygen (O): 15.999 g/mol (each oxygen atom)
To find the total molar mass of HCO₃, we add the atomic masses of all the atoms in the formula:
Molar Mass of HCO₃ = (1 × 1.008) + (1 × 12.011) + (3 × 15.999)
Molar Mass of HCO₃ = 1.008 + 12.011 + 47.997
Molar Mass of HCO₃ = 61.016 g/mol
Therefore, the molar mass of bicarbonate (HCO₃) is approximately 61.016 g/mol.
