1

Household vinegar contains the organic compound acetic acid with chemical formula, $CH_{3}COOH$ . If a vinegar sample contains $0.1024\ moles$ of acetic acid, calculate the percent (mass/mass) of the $CH_{3}COOH$ in the vinegar sample.

Density of vinegar is the following:

$CH_{3}COOH=1.05\frac{g}{mL}$
