Calculate the \( \mathrm{pH} \) of a buffer prepared by mixing
P \( 0.10 \mathrm{~mol} \) of sodium formate and 0.05 mole of formic

W acid in \( 1.0 \mathrm{~L} \) of solution. \( \left(\mathrm{HCO}_{2} \mathrm{H}: \mathrm{K}_{\mathrm{a}}=1.8 \times 10^{-4}\right) \)
(1) \( 1.8 \times 10^{-4} \)
(2) 3.44
(3) 4.05
(4) 5.31
