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.
