Question

Find the relative molecular mass of Na2, Co3 (given Na =23,C=12,o=16)

Answer 1

Answer:

The molar mass of Na2CO3 is 106 g/mole

Explanation:

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.
