What is Molar Mass?

The molar mass of a compound is the mass of one mole of that substance. It is expressed in grams per mole (g/mol) and is calculated by summing the atomic masses of all the atoms in the compound’s formula. For NaHCO3, the molar mass is determined by adding the atomic masses of sodium (Na), hydrogen (H), carbon ©, and oxygen (O).

Calculating the Molar Mass of NaHCO3

To calculate the molar mass of NaHCO3, we need to know the atomic masses of each element involved:

Sodium (Na): 22.99 g/mol
Hydrogen (H): 1.01 g/mol
Carbon ©: 12.01 g/mol
Oxygen (O): 16.00 g/mol

The formula for sodium bicarbonate is NaHCO3, which means it contains one atom of sodium, one atom of hydrogen, one atom of carbon, and three atoms of oxygen. The molar mass is calculated as follows:

Molar mass of NaHCO3 = (1 × 22.99) + (1 × 1.01) + (1 × 12.01) + (3 × 16.00)

Molar mass of NaHCO3 = 22.99 + 1.01 + 12.01 + 48.00

Molar mass of NaHCO3 = 84.01 g/mol
