Question

Calculate the mass percentage of...
H2SO4​

Answer 1

H2SO4...

= 1×2+32×1+16×4

= 2+32+64

= 98u...

Answer 2

Hyyy....

Molecular Mass of Sulphuric Acid (H2SO4) = 98

% composition of Hydrogen = 2/98×100 = 2.01 %

% composition of Oxygen = 64/98×100 = 65.3 %

% composition of Sulphur= 32/98×100 = 32.5 %
