Could someone help me please?

2,4,2

Explanation:

by looking at the subscripts (small number behind the element) you can tell how many of these atoms are presented in the compound.

your compound is C2H4O2

so there are two carbon atoms present, four hydrogen atoms present, and 2 oxygen atoms present.

hope this helps :)
