A buffer solution is prepared by mixing $0.3 \mathrm{M} \mathrm{NH}_{3}$ and $0.1 \mathrm{M} \mathrm{NH}_{4} \mathrm{NO}_{3}$. If $\mathrm{K}_{\mathrm{b}}$ of $\mathrm{NH}_{3}$ is $1.6 \times 10^{-5}$ at $25^{\circ} \mathrm{C}$, then the pH (rounded off to one decimal place) of the buffer solution at $25^{\circ} \mathrm{C}$ is ____ .
