PRE-LAB QUESTIONS 1. A student dissolves 2.006 g of FeSO4-7 H₂O in 40 mL of sulfuric acid and then dilutes it to 100.00 mL in a volumetric flask as described is Procedure steps 3-7. He then uses a pipet to transfer 10.00 mL of this solution into a flask for titration as in Procedure step 11. What mass of FeSO4-7 H₂O was transferred into the titration flask? (Keep this question in mind as you do your calculations for Pre-Lab Question 2 and for your calculations with your own data.) 2. Your partner has completed three acceptable titrations for standardizing the dilute potassium permanganate solution and he gives you all of the data. The solid standard used was FeSO4-7 H₂O, and it was dissolved and diluted to 100.00 mL. a. Calculate the molarities for the trials (Hint: you are going to need the balanced ionic equation and the formula mass of ferrous sulfate heptahydrate.) Mass of Standard Volume of Blank Volume of Standard Initial Buret Reading Final Buret Reading Volume of Titrant Molarity KMnO4 2.047 g 0.04 mL Trial 1 10.00 mL 1.57 mL 19.75 mL Trial 2 10.00 mL 2.15 mL 20.98 mL Trial 3 10.00 mL 1.30 mL 19.33 mL Trial 4 10.00 mL 3.53 mL 21.93 mL b. Examine your partner's results and determine which three trials should be used to determine the average molarity of the permanganate solution; then using the appropriate values calculate the average molarity of the potassium permanganate solution.

All of these things should have spaces in your data table, and they should show up again in your Claim and/or Evidence, depending on how you phrased your Beginning Question. Be sure to show all of your calculations in your Calculations section. Make this section neat and organized, and clearly identify each of the calculations. PRE-LAB QUESTIONS 1.
