The compound adrenaline contains 56.7 % c, 6.56 % h, 28.37% o and 8.28 % n by mass. what is the empirical formula for adrenaline?

- An empirical formula of adrenaline is .

Solution:- Convert given percentages to moles and then calculate the mol ratio to get the simplest whole number ratio of moles of atoms which is the empirical formula of the compound.

= 4.725 mol

= 6.56 mol

= 1.773 mol

= 0.591 mol

let's calculate the mol ratio now. To calculate the mole ratio, we divide the moles of each by moleso f N as it's the least one:

= 8

= 11

= 3

= 1

So, an empirical formula of adrenaline is .
