Answer:
To calculate the molar mass add the atomic mass of each atom in the chemical formula.
Explanation:
For example Molar mass of NaHCO₃ calculated as
Molar mass is the sum of masses of all atom present in formula.
Atomic mass of sodium = 23 g/mol
Atomic mass of hydrogen = 1.008 g/mol
Atomic mass of carbon = 12 g/mol
Atomic mas of Oxygen = 16 g/mol
Molar mass of NaHCO₃ = 23 + 1.008 + 12 + 16× 3
Molar mass of NaHCO₃ = 23 + 1.008 + 12 + 48
Molar mass of NaHCO₃ = 84.008 g/mol
