(CallsOg melar mass-17S g/mol. is a mnirany occurring orgne compound win araoedint propene Aheamy aan daly reqiement ofl vitamin C is 70-90 mg A sweet lie contains 2.05-10 mol of ascorbic acid o determine whether the ascorbic acid in a sweet lme meets the daily requirement calculate the mass of ascorbic acid in 2,85-10 mol of ascorbic ackd Expres the mass in grans to three sigificant figwes w Available HinsExplanation / Answer
Molar mass of Vitamin C = 176 g/mol
Daily requirement of Vitamin C = 70.90 mg
Moles of Vitamin C in sweet lime = 2.85*10^-4 mol
Mass of Vitamin C in sweet lime = moles x molecular weight
= 2.85*10^-4 mol x 176 g/mol
= 0.05016 g x 1000mg/g
= 50.2 mg
Daily requirement of Vitamin C (70.90 mg) > Mass of Vitamin C in sweet lime (50.2 mg)
Vitamin C in a Sweet lime does not meet the daily requirement
Mass of Vitamin C in sweet lime = 0.0502 g
