[answerhappygod]

A solution of NaOH was standardized by titration of a known
quantity of the primary standard potassium hydrogen phthalate, KHP
(FM 204.221). Titration of 0.6930 g of KHP required 32.15mL
of NaOH solution. (8 points)
a. Find the molarity of the NaOH solution.
b. Find the concentration of H2SO4 solution if a 10.00 mL
aliquot of the solution required 36.94 mL of NaOH solution (see
part a) to reach the phenolphthalein end point.
Please do A and B
