It has the unwieldy formula of KHC3H404 This is often written in shorthand notation as KHP If 24.8 mL of a sodium hydroxide solution are needed to neutralize 0.704 grams of KHP, what is the molarity of the sodium hydroxide solution?

Answer 1

Solution A Given mass g KHP (KHGH224) - O-704 goams. molar mass of KHP = 204 g mot volume of solution = 24.8 m2 molarity of Kap- mass of Kapy 1000 volumreof Solutions molar masse kHP mothy 0-7049 204 gmorta 1000 28'45 704 204*284 57936 = 704 mol 2 = 16.122 mol i Since KAP is mono basic and (KHChoyt + K Cg Hyou to To neutralize KHp, nolarity of NaOH needed = molarity of Nash KHE H404 + NOOH → H40 + Mak G&#40f molarsity of NaOH = 0922M) modarity of kHp = molarity of NaOH = 1.499 x 1000 20x gmolt 28.7 1490 mod at 5854.8 - 0.254 mop [ 0.254M)
