During the standardization procedure of the iodine dropper, a student used 10.0 mL of a 1.00 mg.mL standard of Vitamin C. After adding 41 drops of iodine to the 10.0 mL of the standard, the sample was a deep blue. Calculate how many mg of Vitamin C are titrated by each drop of iodine (mg VC/dp l2), from this dropper bottle. The # of drops is an exact #, so it's not taken into consideration when determining the # of sig figs in the calculation. Please show work.
