Question

If the daily allowance for Vitamin C is assumed to be 75.0 mg, how many liters (L) of a 0.002486 M solution of ascorbic acid would be required for a 15.0 day voyage across an ocean?

Answer 1

Answer:

Volumen C6H8O6(sln) = 2.569 L ≅ 2.6 L

Explanation:

vitamin C ≡ ascorbic acid (C6H8O6)

∴ vitamin C/daily = 75.0 mg/d

∴ molar mass C6H8O6 = 176.12 g/mol

solution:

∴ C C6H8O6 = 0.002486 mol/L

⇒ ppm C6H8O6 = (0.002486 mol/L)*(176.12 g/mol)*(1000 mg/g)

⇒ ppm C6H8O6 = 437.834 mg/L

for a 15.0 day:

⇒ Volume C6H8O6(sln) = (75.0 mg/d)*(L/437.834 mg)*(15.0 d)

⇒ Volume C6H8O6(sln) = 2.569 L
