Answer: CH2O
Explanation:
To find the ratio in moles you divide by the
Ar of each element.
Using approximate values:
Ratio in grams
C : H : O
⇒ 40 : 6.6 : 53.4
Ratio in moles
C : H : O
⇒40/12 : 6.7/1 : 53.4/16
⇒3.33 : 6.7 : 3.33
Dividing through by
3.33
⇒ 1 : 2 : 1
So the empirical formula is:
CH2O
