Answer:

C₃H₈O₃

Explanation:

Let's assume we have 100 g of said compound. Then we would have:

  • 39.12 g of C
  • 8.772 g of H
  • 52.11 g of O

Now we convert those masses into moles, using their respective atomic weights:

  • C ⇒ 39.12 g ÷ 12 g/mol = 3.26 mol C
  • H ⇒ 8.722 g ÷ 1 g/mol = 8.722 mol H
  • O ⇒ 52.11 g ÷ 16 g/mol = 3.26 mol O

Then we divide those moles by the smallest number among them:

  • C ⇒ 3.26 mol C / 3.26 = 1
  • H ⇒ 8.722 mol H / 3.26 = 2.68
  • O ⇒ 3.26 mol O / 3.26 = 1

Finally we multiply those numbers by 3, so as to convert the 2.68 of H into an integer:

  • C ⇒ 1 * 3 = 3
  • H ⇒ 2.68 * 3 = 8
  • O ⇒ 1 * 3 = 3

Thus the empirical formula is C₃H₈O₃
