Answer:
C4H8O2
Explanation:
The molar mass of the compound we're looking for is 88.
54.5% of 88 is 4, this is how many carbons will be in the compound.
9.1% of 88 is 8, this is your hydrogens.
and 36.4% of 88 is roughly 3, however if you subtract the previous amounts to round down, you get 2; the oxygen amount.
Combine them all and you get C4H8O2
