I need help with these two questions!!

$1.$What is the $pH$ at the equivalence point in the titration of a $25\mathrm{.}8mL$ sample of a $0\mathrm{.}371M$ aqueous hydrocyanic acid solution with a $0\mathrm{.}493M$ aqueous potassium hydroxide solution?

$pH=$

$2.$When a $21\mathrm{.}6mL$ sample of a $0\mathrm{.}360M$ aqueous nitrous acid solution is titrated with a $0\mathrm{.}473M$ aqueous sodium hydroxide solution, what is the $pH$ at the midpoint in the titration?

$pH=$
