The empirical formula of the compound containing 79.8% carbon and 20.2% hydrogen is CH₃

Data obtained from the question

Carbon = 79.8%
Hydrogen= 20.2%
Empirical formula =?

How to determine the empirical formula

Divide by their molar mass

C = 79.8 / 12 = 6.65

H = 20.2 / 1 = 20.2

Divide by the smallest

C = 6.65 / 6.65 = 1

H = 20.2 / 6.65 = 3

Thus, the empirical formula of the compound is CH₃
