The molar mass of a compound defines the mass of 1 mole of that particular substance and the 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.
Since sodium carbonate contains two atoms of 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.
The molar mass of Na2CO3 is 106 g/mole.
