Question

2. A compound is found to contain 24.8% carbon, 2.0% hydrogen, and
73.2% chlorine with a molecular mass of 96.9 g/mol. What is the molecular
formula?​

Answer 1

carbon= 24.8/12 = 25/12 = 2.08

hydrogen = 2/2 = 1

chlorine = 96.9/35.5 = 2.72

EFM = 2.08/1 = 2.08, 1 / 1= 1, 2.72/1

Answer 2

Explanation:

step 1: calculation of emperical formula

emperical formula : CHCL

step:2 calculation of molecular formula

therefore, molecular formula: C2H2CL2
