Acetic acid has the molecular formula CH3COOH. How many atoms of oxygen are there in 60 grams of acetic acid?​

1.2046x10²⁴ atoms

Explanation:

First we convert 60 grams of acetic acid into moles of acetic acid, using its molar mass:

Then we double the number of acetic acid moles, as there are two oxygen moles per acetic acid mole.

Finally we convert moles into number of atoms, using Avogadro's number:

the answer is d. 74.02
