During Lab 4, you are titrating a sample of new orange juice to determine its ascorbic acid (aka vitamin C) content. You have previously determined an experimental conversion factor of 0.26 mg ascorbic acid/mL dye using an ascorbic acid standard. After measuring out 5.16 mL of your orange juice sample and ~10 mL of 3% metaphosphoric acid to a graduated cylinder, you dilute the solution to 50.33 mL with DI water. You finally dispense 10.87 mL of the diluted solution into an Erlenmeyer flask, add 4 drops of HCl, and use 6.48 mL of dye to reach the equilibration point. How much ascorbic acid (mg) is in your concentrated orange juice sample? The molecular weight of ascorbic acid is 176.12 g/mol.
