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