The formula for acetic acid is ch3cooh. seana wants to know how many oxygen atoms are in 0.12 moles of acetic acid. o a. 1x 10^25 atoms o b. 60 atoms oc. 14x 10^23 atoms o d. 4.0 x 10^-24 atoms o e. 7.2 x 10^22 atoms

c. 1.4 x 10²³ oxygen atoms

Explanation:

The number of oxygen atoms in one molecule of CH₃COOH is 2.

Avogadro's constant relates the number of molecules in one mole:

6.022 × 10²³ mol⁻¹

Thus, the number of oxygen atoms in one molecule of acetic acid can be converted to the number of oxygen atoms in one mole of acetic acid:

(2 oxygen atoms / molecule)(6.022 × 10²³ molecule / mol) = 1.204 x 10²⁴ atoms per mole

Finally, the number of oxygen atoms in 0.12 moles of acetic acid are calculated:

(1.204 x 10²⁴ atoms / mol)(0.12 mol) = 1.4 x 10²³ atoms/mol
