Final answer:
The empirical formula of C22H44 is C11H22.
Step-by-step explanation:
The empirical formula of a compound represents the simplest whole number ratio of the atoms present in the compound. To determine the empirical formula of C22H44, we need to find the simplest whole number ratio of carbon and hydrogen atoms.
Step 1: Divide the subscripts of carbon and hydrogen by their greatest common divisor to simplify the ratio. The greatest common divisor of 22 and 44 is 22.
22 ÷ 22 = 1
44 ÷ 22 = 2
Therefore, the simplest whole number ratio of carbon and hydrogen atoms is 1:2. The empirical formula of C22H44 is C11H22 (option b).
