Question

There are many compounds that contribute to the overall aroma of a banana. The primary compound is called isoamyl acetate and consist of 60.58% C, 7.07% H, and 32.28%O. What is the empirical formula

Answer 1

Explanation:

Let the mass of isoamyl acetate be 100g.

Moles of Carbon = 60.58/12 = 5.048mol

Moles of Hydrogen = 7.07/1 = 7.07mol

Moles of Oxygen = 32.28/16 = 2.018mol

Mole Ratio of C : H : O

= 5.048 : 7.07 : 2.018

= 5 : 7 : 2.

Hence the empirical formula of isoamyl acetate is C5H7O2.
