If a solution of unknown concentration of HCl weighs 22.64 g and takes 19.5 mL of 0.221MKOH to be neutralized, what is the molarity of the acid? 1) 0.177MHCl 2) 177MHCl 3) 0.221MKOH 4) 0.221MHCl Question 2 (5 points) Suppose a sodium hydroxide solution were to be standardized against pure solid primary standard grade KHP. If 0.843 g of KHP requires 18.3 mL of the sodium hydroxide solution to reach a phenolphthalein endpoint, what is the molarity of the NaOH solution? 1) 226MNaOH 2) 0.0183MNaOH 3) 204MNaOH 4) 0.226MNaOH 5) 0.268MNaOH
