Question

the empirical formula of a molecule is C4 H3 O2 and the vapour density is 83 what is its molecular formula​

Answer 1

Answer:

C8H6O2

Explanation:

Emperical formula= C4H3O2

vapour density=83. molecular formula=?

molecular weight= 2× vapour density

= 2×83

= 166

molecular formula = molecular weight. × E.F

emperical formula weight

= 166 = 2

83

= C8H6O4
