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:
∴ <em>C</em> 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
Answer:
3 carbohydrate
Explanation:
Carbohydrates are among the major macromolecules, others being proteins, lipids and nucleic acids. They contain carbon, hydrogen and oxygen atoms in their structure.
(I hope this help if not im sorry)
Check your chemistry textbook (or class notes) concerning molar mass, then look up the value for oxygen.
Then divide Avogadro’s number into the given amount of atoms, to find the number of moles.
Then combine this result appropriately with the molar mass, and voilà!
…Then reconsider posting homework questions without showing the work you have already done.
