Needed urgently but strictly handwritten only do fast as possible

Calculate the pH of a solution prepared by mixing 20.00 mL of the 0.140 M benzoic acid solution
(Ka-6.46 x 105) with 5.00 mL of 0.200 M NaOH. (BEFORE using ICE to solve for the pH of this
mixture, think about whether the pH should be less than 7 equal to 7 or greater than 7 simply by
comparing the moles of benzoic acid and the NaOH.)
