Using the amount of each element you calculated in part A, calculate the ratios of the elements to each other to determine the empirical formula. Select the correct answer from each drop-down menu to complete the empirical formula.

C2H6O1

Explanation:

Divide the number of moles of each element by the smallest number of moles, which is 9.69 moles.

Divide the number of moles of carbon by 9.69:

19.3 mol/ 9.69 mol ≈ 2.

Divide the number of moles of hydrogen by 9.69:

57.5 mol/ 9.60 mol ≈ 6.

Divide the number of moles of oxygen by 9.69:

9.69 mol/ 9.69 mol = 1.

So, the empirical formula of the unknown compound is C2H6O.
