Name: Partner: Determining the Molar Mass of an Acid 2. Prelab (due at the beginning of lab) (14 points) 1. In the first part of this experiment you will be preparing a sodium hydroxide solution. Assuming that you added exactly 25.0 mL of 2.25 M NaOH to exactly 500.00 mL of deionized water, calculate the molarity of this solution. Assume that the volumes are additive. Show your work (6 points) 2. Assuming that the mass of KHP (KHC H&04) is 0.250 g: a. Calculate the number of moles of KHP. This will be equal to the number of moles of NaOH that will react with KHP in part A. b. From the number of moles of NaOH and the molarity calculated in question 1, calculate the volume of NaOH that will be used in this titration. Show your work. (8 points)
