Answer :
Answer:
CH2O
Explanation:
the empirical formula of a compound is determined by obtaining the moles of each element and then divided each element by the lowest value. represents the simplest ratio in which atoms that form a chemical compound.
for the molecular formula C2H4O2; its empirical formula would be:
moles C: 2/2 = 1
moles H: 4/2 = 2
moles O: 2/2 = 1
⇒ empirical formula: CH2O
