Can the mercury cation (Hg2+) oxidize silver metal to aqueous silver cation? If so, would the reaction equation be as follows: 2 Ag(s) + Hg2+(aq) ---> Hg(l) + 2 Ag+(aq) Thank you!

URGENT!!! How many grams of sodium benzoate (NaC6H5CO2) must be added to 500 mL of 0.15 M benzoic acid (HC6H5CO2) to make a buffer solution with pH of 5.0? Assume no volume change upon sodium benzoate dissolution. Ka = 6.46 x 10-5 How would I go about this question?
