Given:
 
Weight of Sulphuric acid = 9.8 g
 
Molar space mass space of space straight H subscript 2 SO subscript 4 space equals space 98 space straight g divided by mol 2 space straight H space atoms space equals space open parentheses 1 cross times 2 close parentheses space equals space 2 percent sign space of space straight H space equals space 2 over 98 cross times 100 space space space space space space space space space space space space equals space 2.04 percent sign 1 space straight S space equals space 32 percent sign space of space straight S space equals space 32 over 98 cross times 100 space space space space space space space space space space space space equals space 32.65 space percent sign 4 space straight O space equals space open parentheses 16 cross times 4 close parentheses equals space 64 percent sign space of space space straight O space equals 64 over 98 cross times 100 space space space space space space space space space space space space space equals 65 space percent sign
 
Percentage composition of H in sulphuric acid is 2.04%
 
                                       S in sulphuric acid is 32.65%
                                       
                                       o in sulphuric acid is 65%
