2.88 x 10^-4 mol x 176 g/mol = 0.05072256 g = 0.0507 g 

50.7 mg does not meet the daily requirement.

Answer : 50.7 mg

Explanation : One mole of ascorbic acid molecule [tex] C_{6}H_{8}O_{6} [/tex] contains molar mass as 176 g/mol. When a person consumes a sweet lime which has the ascorbic acid content as [tex] 2.86 X 10^{- 4} mol [/tex]; the total requirement of vitamin C for the adult human will be equal to;

[tex] 2.86 X 10^{- 4} X 176 [/tex] = 0.050688 g = 50.7 mg

This clearly shows that consuming one sweet lime daily will not fulfill the requirement of vitamin C for the human adult body, as the requirement range is from 70-90 mg daily.
