what is the chemical formula for this question?
we're learning about iodimetric analysis and the instructor is helpless and I can't figure out how to solve this problem

1) calculate mol iodine used
2) from the mol iodine and the balanced chemical equation calculate the mol vitamin C in the sample
3) from the mol vitamin C calculate the mass of vitamin C
You don't give a chemical equation - you need to have that to do the calculation
