Give complete answers to all pre-lab questions in your laboratory notebook. (The reader should be able to interpret the answer without referring to the lab.) For numerical calculations, show all work with units in each step. Report final values to correct sig figs with correct units. 1. Explain the difference between equivalence points and end point. 2. Write the chemical formula of acetic acid and then calculate its molar mass. 3. Write the balanced chemical equation between acetic acid and sodium hydroxide solution. Include states for all reactants and products. 4. How many milliliters of 1.50 M NaOH are required to prepare 500.0 mL of 0.785 M NaOH solution? State the dilution equation and show all related work. 5. Our primary standard is potassium hydrogen phthalate. This is abbreviated as KHP, which is NOT its formula. a. Write the chemical formula of KHP and calculate its molar mass. b. Calculate the molarity of sodium hydroxide solution if 31.45 mL are needed to titrate 0.6570 g sample of KHP. Show all related work. Hint: Mole ratio between KHP and sodium hydroxide is 1:1.

I need help finding out how to the sample calculations because I cannot figure out the moles of NaOH, moles of oxalic acid, and molarity of oxalic acid in sample. I believe the molarity of oxalic acid is 0.04 M based on what I have seen but I have no clue how you would get it or if it’s even right. Basically just need help with B. Sample Calculations
