Question

find the molecular formula of the compound with molar mass 78g mol^-1 and empirical formula CH​

Answer 1

Answer:

$C_{6} H_{6}$ answer

Explanation:

Empirical formula= CH

let,the molecular formula be =  $(CH)_{n}$

          Therefore molecular mass=$13_{n}$

Therefore as the question given below ,

                           $13_{n}$ =78

⇒ n= 6...........(i)

so, molecular formula=  $(CH)_{n}$

                                    = $CH_{6}$

                                    =$C_{6} H_{6}$ answer
