Calculate the \( \mathrm{pH} \) of a solution prepared by mixing \( 50.0 \mathrm{~mL} \) of \( 0.200 \mathrm{M} \mathrm{CH}_{3} \mathrm{COOH} \) and \( 50.0 \mathrm{~mL} \) of
\( 0.100 \mathrm{M} \mathrm{NaOH} .\left[\mathrm{K}_{\mathrm{a}\left(\mathrm{CH}_{3} \mathrm{COOH}\right)}=1.8 \times 10^{-5}\right] \)
\( \mathrm{P} \)
