The percentage of pyridine $\displaystyle \left(\mathrm{C}_5 \mathrm{H}_5 \mathrm{~N}\right)$ that forms pyridinium ion $\displaystyle \left(\mathrm{C}_5 \mathrm{H}_5 \mathrm{~N}^{+} \mathrm{H}\right)$ in a $\displaystyle 0.10$ M aqueous pyridine solution ($\displaystyle K_{\mathrm{b}}$ for $\displaystyle \mathrm{C}_5 \mathrm{H}_5 \mathrm{~N}=1.7 \times 10^{-9}$) is
