<u>Answer:</u> The correct option is 1 mole of acetic acid was required for 2 moles of sodium bicarbonate

<u>Explanation:</u>

We are given:

$NaHCO_3+CH_3COOH\rightarrow CH_3COONa+H_2CO_3$

From the stoichiometry of the reaction:

1 mole of sodium carbonate reacts with 1 mole of acetic acid in vinegar.
