Question

If sodium is 14.28%, sulphur is 9.92%, hydrogen is 6.20%. But compound is consist of sodium,sulphur,hydrogen and oxygen.Then how we can find the %age of oxygen?​

Answer 1

% of sulphur=9.92%

%of sodium=14.28%

% of hydrogen=6.20%

thus, % of oxygen=[100-(9.92+14.28+6.20) ]%

=100-27.40%

=72.60%
