Answer:
The quantity of ascorbic acid found in sweet lime of 49.6 mg does not meet the daily requirement.
Explanation:
To determine the mass of ascorbic acid knowing the number of moles we use the following formula:
number of moles = mass / molecular weight
mass = number of moles × molecular weight
mass of ascorbic acid = 2.82 × 10⁻⁴ × 176
mass of ascorbic acid = 496 × 10⁻⁴ g = 0.0496 g = 49.6 mg
daily requirement of ascorbic acid = 70 - 90 mg
The quantity of ascorbic acid found in sweet lime of 49.6 mg does not meet the daily requirement.
Answer:
49.7 mg of Ascorbic acid do not meet the daily requirement.
Explanation:
The conversions are
Moles to mass, by multiplying with molar mass.
Molar mass is the mass of 1 mole of the substance.
Its unit is gram per mole g/mol
Ascorbic acid ([tex]C_6H_8O_6[/tex]) contains 6, C atoms 8, H atoms and 6, O atoms .
We find the molar mass of the compound by just adding the atomic mass of the atoms present in it
Molar mass of Ascorbic acid
[tex]=(6\times 12.0107)+(8\times 1.00784)+(6\times 15.999)[/tex]
=176.124 g/mol(Given)
Mass of Ascorbic acid = Moles × Molar mass
[tex]=2.82 \times 10^{-4} mol \times 176.124 g/mol[/tex]
=0.0497 g
We know
1 g = 1000 mg
So
[tex]0.0497g \times 1000mg/1g=49.7mg[/tex] VITAMIN C
The required quantity for an Adult is 70 to 90mg.
So 49.7 mg of Ascorbic acid do not meet the daily requirement.(Answer)
