Question

An analytical chemist has determined by measurements that there are 96.5 moles of carbon in a sample of acetic acid. how many moles of oxygen are in the sample

Answer 1

The formula of acetic acid is CH3COOH => C2H4O2.

So, the acetic acid has the same number of atoms of carbon (C) than of oxygen (O).

Therefore, the sample that contains 96.5 moles of carbon, will contain also 96.5 moles of O.

Answer: 96.5 moles of oxygen.
