229754 A buffer solution prepared in which the concentration of $\mathrm{NH}_3$ of $0.30 \mathbf{M}$ and the concentration of $\mathrm{NH}_4^{+}$is 0.20 M. If the equilibrium constant $\mathrm{K}_{\mathrm{b}}$ for $\mathrm{NH}_3$ equals $1.8 \times 10^{-5}$, what is the $\mathrm{pH}$ of this solution ? $(\log 2.7=0.43$ )
