A 3.180 g sаmple cоntаining KHP wаs dissоlved in apprоximately 50.00 mL of water. This resulting solution required 30.180 mL of 0.250 M NaOH solution to neutralize it. What percent of the solid sample was pure KHP? (Assume no other acids are present. KHP = Potassium hydrogenphthalate KHC8H4O4; the molar mass= 204.22 g/mol) (Hint: Balance the reaction. KHP has ONE acidic H, hence, the reaction ratio is 1:1)
