각 성분의 몰수 계산
> 74.95 g / (12.0107 g/mol) = 6.24027 mol C
> 11.74 / 1.00794 = 11.64752 mol H
> 13.31 / 15.9994 = 0.8319062 mol O
몰수의 가장 작은 정수비 계산
C : H : O = 6.24027 : 11.64752 : 0.8319062
= 6.24027/0.8319062 : 11.64752/0.8319062 : 0.8319062/0.8319062
= 7.5 : 14 : 1
= 15 : 28 : 2
---> 실험식 = C15 H28 O2
답: C15H28O2
