Question

What is the emperical formula of a compound that contains 40 percent carbon, 6.7 percent hydrogen, and 55.3 percent oxygen by mass?

Answer 1

The ratio of the no. of atoms of C : H :O = 40/12 : 6.7/1 : 55.3/16 = 3.33 : 6.7 : 3.4 = 1 : 2 : 1. Hence the empirical formula of the compound is CH2O.
