3. A chemistry student is doing a titration lab in D314 and needs to make up 2 liters of NaOH for the class and standardize the NaOH with the organic acid KHP (MW 204.2 g/ mol). The instructions say 5 grams/ liter of NaOH pellets which is ~ 0.1 M by the molar mass of NaOH. The student weighs out~ 10 grams of NaOH and dissolves it in 2 liters of water. The student then weighs out 0.4120 g of KHP and puts the organic acid in 50 mL of water and adds ~ 3 drops of 1% phenolphthalein indicator. To reach the endpoint (pink) where moles KHP are used up with NaOH, he adds 17.5 mL of the NaOH from the I N
