Question

Calculate the molar mass of Na2CO3 (in g/mol).Is this correct?105.987

Answer 1

The molar mass: is the sume of all the atomic masses that make up the molecule.

2 x atomic mass of Na = 2 x 22.989 = 45.978

1 x at. mass of C = 12.01 = 12.01

3 x at. mass of O = 3 x 15.999 = 47.997

Na2CO3 = 105.985

Your answer was correct!
