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

Answer:

C9 H13 N O3  

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
