 An organic  compound having carbon, hydrogen and sulphur contains 4% of sulphur . The minimum molecular weight of the compound is 

Answer:

Explanation:

The minimum  m. wt. must contain at least one S atom

 $\therefore$      % S=( weight of one S- atom )/ ( mminimum m.wt) x 100

 4=( 32/ minimum m .wt )x 100

 minimum m.wt =  $\frac{32}{4}\times 100=800$
