MHT CET Chemistry question

If a compound on analysis was found to contain C = 18.5%, H = 1.55%, Cl = 55.04% and O = 24.81% then its empirical formula is

Answer: (D)

Solution

Moles: C 18.5/12 = 1.54, H 1.55/1 = 1.55, Cl 55.04/35.5 = 1.55, O 24.81/16 = 1.55, giving the simplest ratio C : H : Cl : O =
