Answer:

It contains 75g of acetic acid.

Step-by-step explanation:

With the percent mass (15%) and the mass of the solution of vinegar, we can calculate the amount of acetic acid, using the percent by mass formula:

$\begin{gathered} PercentByMass=(MassOfSolute)/(MassOfSolution)*100\% \\ 15\%=(MassOfSolute)/(500g)*100\operatorname{\%} \\ \frac{15\%}{100\operatorname{\%}}*500g=MassOfSolute \\ 75g=MassOfSolute \\ \end{gathered}$

So, it contains 75g of acetic acid.
