C - 77.87% H- 11.76% O - 10.37% (Balance from 100%)
divide through by respective atomic masses:-
C : H : O
77.87 /12 : 11.76/1 : 10.37/16
6.49 : 11.76 : 0.65
divide through by smallest ratio (0.65)
6.49/0.65 : 11.76/0.65 : 0.65/0.65
9.98 ; 18.09 ; 1.
approximate these ratios to
10 ; 18 ; 1.
hence empirical formula is:-
C10H18O
