The molar mass of a compound defines the mass of 1 mole of that particular substance and number of grams per mole of a compound. In other words, the molar mass is the total mass of all the atoms in grams that make a mole of a particular molecule.

Sodium Carbonate :

• Since sodium carbonate contains two atoms sodium, one atom of carbon and three atoms of oxygen. The molecular weight would be

➠ Na : 2 x 23.0 = 46

➠ C : 1 x 12.0 = 12

➠ O : 3 x 16 = 48

• When we add up the total values i.e, 46 + 12 + 48 = 106

➠ Therefore, the molar mass of Na2CO3 is 106 g/mole.

Answer:

The molar mass of Na2CO3 is 106 g/mole.
