Answer:

molecular formula:C2H4. molecular mass:28. emperical mass:14

Explanation:

given,

emperical formula:CH2

emperical mass= 12+2*1=14

molecular mass/emperical mass=2

molecular mass/14=2

molecular mass=28.

(CH2)n will be he molecular formula.

we know molecular mass=28

(12+2)*n=28

n=2

molecular formula= (CH2)n

C2H4
