How many mg of ascorbic acid, C6H8O6 are present in the juice aliquot? _5.38_____(can you please show how to calculate this answer) How many ml of this juice would Bich have to drink in order to meet the daily recommended intake (DRI)?__126__ (During exercise when the body lacks an adequate supply of oxygen to support energy production, the pyruvate that is produced from the breakdown of glucose is converted into lactate. High lactate levels can lead to acidity in the muscle cells as some of the lactate hydrolyzes to lactic acid. The dissociation of lactic acid to lactate is shown in the reaction. Lactic acid has a p?apKa of 3.86.3.86. A solution containing a mixture of lactic acid and lactate was found to have a pH of 3.24.3.24. Calculate the ratio of the lactate concentration to the lactic acid concentration in this solution.An unkown solvent has a formula of C4H8O and molecular weight of 72.11 g/mol.
