find molecular formula

Asked by  | 4th Mar, 2009, 07:49: AM

Expert Answer:

H = 2.7 /1 = 2.7

Cl = 48.3 / 35.5 =1.36

C = 49 /12 =4.08

H =2.7 /1.36 =2

Cl =1.36 /1.36 = 1

C =4.08 / 1.36 =3

so, the emperical formula = C3H2Cl

The emperical formula mass =73.5

n= 147 / 73.5 2

so the  molecular formula = C6H4Cl2
