| Mass of ascorbic acid (g) | Given | 0.549 | 0.584 |
| Mass of ascorbic acid (mg) | mass in g x 1000 | 549 | 584 |
| Initial burette reading (mL) | Given | 0.25 | 0.10 |
| Final burette reading (mL) | Given | 27.80 | 26.95 |
| Volume of KIO3 (mL) | final burette reading - initial burette reading | 27.55 | 26.85 |
| mg Vit. C / mL KIO3 | mass of ascorbic acid in mg / volume of KIO3 in mL | 19.927 | 21.750 |
Average mg Vit. C / mL KIO3 = (value from trial 1 + value from trial 2) / 2 = (19.927+21.750) / 2 = 20.838.

I am doing a titration lab using sodium thiosulfate pentahydrate to determine an amount if iodine. I'm having issues setting up the balanced equation to determine the mole ratio of iodine to thiosulfate. I used an approximate .080M solution of Sodium Thiosulfate and then titrated into a flask containing 25mL of KIO3, 20mL H2SO4 and 2g KI. Final mL of Sodium Thiosulfate used to complete titration was 37.36mL of Na2S2O3 5H20. I then did the same process for a 25mL...
