Analyisis Of Compound (%)
C=72.15 H=7.08 N=4.68 O=16.03
What is it?

Explanation:

Ratio of C : H : N : O  in grams

=  72.15 : 7.08 : 4.68 : 16.03 in grams

Ratio of C : H : N : O in moles

72.15/12 : 7.08/1 : 4.68/14 : 16.03/16 in moles  

6.01 : 7.08 : .334 : 1.00

6.01/ .334  : 7.08/.334 : .334/.334 : 1.00/.334   in moles

18 : 21.19 : 1 : 3

18 : 21 : 1 : 3

empirical formula = C₁₈H₂₁NO₃
