Answer: The molar mass of Sodium carbonate (Na2CO3) is 105.998 gram per mole.
Molar mass refers to the mass of the one mole of that compound as well as the number of grams per mole of that substance.
It is clear that the atoms of carbon, sodium and oxygen together form the Sodium carbonate compound in the number of one, two and three respectively. Hence Molar mass of sodium carbonate when taking approx. values will be –
Na: 2 x 23.0 or 46 g/mol
C: 1 x 12.0 or 12 g/mol
O: 3 x 16 or 48 g/mol
All of which adds up to 106 approx. and hence the molar mass of sodium carbonate will be 106 g/mole (approx.).
