Molar Mass Of Phosgene And Empirical Formula?

i know that the elemental composition is
12.14% C
16.17% O
71.69% CI
molar mass is 98.90g/mole
THANK YOU IN ADVANCE!

Moles C = 12.14 g / 12.011 g/mol =1.01
Moles O = 16.17 g / 15.9994 g/mol = 1.01
Moles Cl = 71.69 g / 35.453 g/mol =2.02
we divide by the smallest number
COCl2 is the empirical formula ( MM = 98.90 ) so it is also the molecular formula
