Question:

Calculate the mass percent of different elements present in sodium sulphate (Na2SO4).

Answer:

The molecular formula of sodium sulphate is (Na2SO4).

Molar mass = atomic mass of Na(23) + atomic mass of S(32.066) + atomic mass of O(16)

Molar mass of (Na2SO4) = [(2 × 23.0) + (32.066) + 4 (16.00)] = 142.066 

Mass percent of an element 

 

∴ Mass percent of sodium: 

 

Mass percent of sulphur:

 

Mass percent of oxygen:
