Question

What is the molar mass of Na2CO3?

60.0 g/mol
O 106.0 g/mol
118.0 g/mol
141.0 g/mol

Answer 1

The required molar mass is 106.0 g/mol

Step-by-step 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
