Pertama, cari Mr CO₂= Ar C + 2 Ar 0
                               = 12 + 2 (16)= 12 + 32 = 44
Massa C dalam CO₂ = 1 x 12/ 44 x 88 = 24 gram
Massa H dalam H₂O = 2/18 x 54 = 6
Massa O = 46 - (24+6) = 46- 30=16
mol C : mol H : mol O
= massa C/ Ar C : massa H/ Ar H : massa O/Ar O
= 24/12 : 6/1 : 16/16
= 2 : 6 :1
jadi, rumus empirisnya = C₂H₆O
