Question

The hormone epinephrine is released in the human body during stress and increases the body's metabolic rate. Epinephrine, like many biochemical compounds, is composed of carbon, hydrogen, oxygen, and nitrogen. The percentage composition of the hormone is 59.0% C, 7.15% H, 26.2% O, and 7.65% N. Determine the empirical formula.

Answer 1

C9 H13 N O3

Step-by-step explanation:

Carbon mole wt = 12

59 /12 = 4.917

Hydrogen mole wt = 1

7.15 / 1 = 7.15

Oxygen mole wt = 16

26.2 / 16 = 1.6375

Nitrogen mole wt = 14

7.65 / 14 = .5464

Now divide the numbers by the smallest found

Carbon 4.917 / .5464 = 9

Hydrogen 7.15 / .5464 = 13

Oxygen 1.6375 / 3

Nitrogen .5464 /.5464 =1 emp form C9 H13 O3 N
