A student has 100.0 mL of an unknown solution of Vitamin C. She removes 1.00 mL of this solution, dilutes it to 50.0 mL, and titrates this second solution with an iodine solution solution that 8.5x1^-4 M. 6.60 mL of iodine solution is required to reach the endpoint. 1. How man...
Chemistry
in step 2 aren't you supposed to divide by the molar mass of vitamin C (176.12)?
Chemistry
would 5.61x10^-5 make sense for the molarity for the original unknown sample of vit C solution prior to dilution?

Nevermind. i figure it out. Thank you so much for your help!
Chemistry
to find the molarity of the original vit C do you just divide the moles found in 1 divided by 0.001 L or 1.0 mL?
Chemistry
to find the total moles of iodine, do you just multiple 8.5x10^-4 by .00660 L?
Chemistry
we are not given the molar mass of the vit. C. how are we supposed to find the milligrams of vit C are in the orginal sample?
