Vitamin C contains the elements C, H, and O. It is known to contain 40.9% C and 4.58% H by mass. The molar mass of vitamin C has
soldier1979 [14.2K]

Answer:

C₆H₈O₆

Explanation:

First off, the<u> percent of oxygen by mass</u> of vitamin C is:

  • 100 - (40.9+4.58) = 54.52 %

<em>Assume we have one mol of vitamin C</em>. Then we would have <em>180 grams</em>, of which:

  • 180 * 40.9/100 = 73.62 grams are of Carbon
  • 180 * 4.58/100 = 8.224 grams are of Hydrogen
  • 180 * 54.52/100 = 98.136 grams are of Oxygen

Now we <u>convert each of those masses to moles</u>, using the <em>elements' respective atomic mass</em>:

  • C ⇒ 73.62 g ÷ 12 g/mol = 6.135 mol C ≅ 6 mol C
  • H ⇒ 8.224 g ÷ 1 g/mol = 8.224 mol H ≅ 8 mol H
  • O ⇒ 98.136 g ÷ 16 g/mol = 6.134 mol O ≅ 6 mol O

So the molecular formula for vitamin C is C₆H₈O₆
