Answer:

#CH_2O#

Explanation:

Carbon weight=12 grams
Hydrogen weight=1 gram
Oxygen weight=16 grams

C to H ratio (mass)=6
Therefore for each carbon, you have two units of hydrogen
(#12/2=6#).

So far it is #CH_2# but also you have oxygen.

C to O ratio is #3/4#
Since for 1 Carbon (12 grams), you need some oxygen:
#C/O=3/4#
where C=12 grams (for one mole)

#O=(12*4)/3#
#O=16# grams

Exactly Oxygen has a weight of 16 grams per mole.

Therefore your formula for this case is;

#CH_2O#

where you have a molecular weight of 30 grams per mole.

Your formula is #CH_2O#
