What is the molecular formula of the molecule that has an empirical formula of c2h2o and a molar mass of 252.22 g/mol?

Ok I got it wrong I think but I'm too lazy to delete all my hard work s merry Christmas?
Molar masses of
C = 12.0107
H = 2.016
O = 15.999
Now what we gots tuh do is take the masses and add them together, but we have to add 2 carbons and 2 oxygens because we are trying to find the molar mass of the empirical formula. So...
2(12.0107)+2(2.016)+15.999
24.0214+4.032+15.999 = 44.0524
Now that we have the molar mass of the empirical formula, we divide the 252.22 by it.
252.22/44.0524 = 5.7254
72.0642+12.096+95.994

It's either 3 or that ,,but if not than choose 4
