SCIE 131 What is the molarity of ascorbic acid?
Aqueous (ascorbic acid, C6H8O 6 (aq) reacts with aqueous diatomic elemental bromine, Br2(aq) according to the following unbalanced equation:
C6H8O6(aq) + Br2 (aq) → C6H6O6(aq) + HBr(aq) .
a) Write the balanced equation, and use it to solve the problems below:
(b) A 251 mL sample of ascorbic acid requires 332 mL of a 0.345 M Br 2 solution for reaction. How many moles of ascorbic acid are in the sample?
(c) How many milligrams of ascorbic acid are in the sample?
(d) What is the molarity of ascorbic acid?
(e) If a person wanted to consume 500. micrograms of ascorbic acid, how many ounces of the acid would that person need to consume?
(4 qts = 128 fluid ounces; 1L = 1.057 qt; 1.00 g = 1.00 x 106 micrograms)
