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 2.81×10⁻⁴ 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 2.81×10⁻⁴ mol of ascorbic acid.

Express the mass in grams to three significant figures.

Answer #1

no of moles of ascorbic acid = 2.81*10^-4 mole

gram molar mass of ascorbic acid = 176g/mole

mass of ascorbic acid = no of moles * gram molar mass

= 2.81*10^-4*176

= 0.0495g

= 4.95*10^-2 g >>>>answer
