A 25.00 ml pipette sample of 1.50 mg/ml ascorbic acid solution was titrated with an iodine solution, requiring 31.75 ml of the iodine solution to reach the end-point. This same iodine solution was used to titrate 25.00 ml of fruit juice, requiring 29.34 ml to reach the end-point. What is the concentration of ascorbic acid in the fruit juice sample in mg/ml?
