The empirical formula of a chemical compound is the simplest positive integer ratio of atoms present in a compound. To find empirical formula simple ratio of atoms to be known as follows:

Element	Percentage	Atomic mass	Relative no. of atoms	Simple ratio of atoms	Simplest whole number ratio
C	60%	12	‌ 60 12 =4.99	‌ 4.99 222 =2.25×4	9
H	4.48%	1	‌ 4.48 1 =4.48	‌ 4.48 2.22 =2.02×4	8
O	35.53%	16	‌ 35.53 16 =2.22	‌ 2.22 2.22 =1×4	4

Hence, empirical formula will be C9H8O4.
