A buffer with a pH of $4.34$ contains $0.330 \textrm{ M}$ of sodium benzoate and $0.240 \textrm{ M}$ of benzoic acid.

What is the pH of the solution after the addition of $0.074 \textrm{ mol}$ of $\textrm{HCl}$ to a final volume of $1.30 \textrm{ L}$?

Assume that any contribution of $\textrm{HCl}$ to the volume is negligible.
