Ascorbic acid, or vitamin c (c6h8o6, molar mass = 176 g/mol), is a naturally occurring organic compound with antioxidant properties. a healthy adult’s daily requirement of vitamin c is 70-90 mg. a sweet lime contains 2.82×10−4 mol of ascorbic acid.
to determine whether the ascorbic acid in a sweet lime meets the daily requirement, calculate the mass of ascorbic acid in 2.82×10−4 mol of ascorbic acid.
