Answer:

The required molar mass is 106.0 g/mol

Explanation:

We know,

Molar mass of Na = 23 g/mol

Molar mass of C= 12 g/mol

Molar mass of O= 16 g/mol

∴Molar mass of Na2CO3 = {(23 X 2) + 12+ (16 X 3)}  g/mol

                                          = (46 + 12 + 48) g/mol

                                          = 106   g/mol

So, the required molar mass is 106.0 g/mol
