Question

What is the molecular formula of a compound with an empirical formula of ch and a molar mass of 78. 1 g/mol?.

Answer 1

answer is in the explanation

Step-by-step explanation:

Answer. Explanation: ->So, molecular formula = (CH)n = (CH)6 =C6H6; in this case we substituted the calculated value of n. ->Therefore, the molecular formula of the compound having the molecular weight 78 g/mol is (D) - C6H6.
