A vitamin C tablet was dissolved in 50.0 mL of water. The resulting solution was titrated to the equivalence point with 28.5 mL of 0.100 M I3− solution. What is the starting mass of the tablet assuming the tablet is 100% vitamin C?
I found the moles in I3- to be .00285. and the ratio of triodide to Vitamin C is 1:1. I found that there is 176.124 grams of Vitamin C. Now what should I do?

To find the starting mass of the tablet, you need to multiply the moles of Vitamin C (0.00285) by the molar mass of Vitamin C (176.124 g/mol). This gives you a result of 0.5067 g, which is the starting mass of the tablet.
