Question

calculate the mass percent of different elements present in sodium sulphate. ​

Answer 1

Sodium Sulphate = Na2SO4

Total Mass = 142 g/mol

Mass of Na = 46

% of Na = 46/142 x 100

             = 32.39 %

Mass of S = 32

% of S = 32/142 x 100

             = 22.53 %

Mass of O = 64

% of O = 64/142 x 100

             = 45.07 %

Hope this helps! :)
