The compound adrenaline is released in the human body in times of stress. It was found by experiment to have the composition 56.8 % C, 6.50 % H, 28.4% O and 8.28% N. What is the empirical formula of adrenaline?

Explanation

To find the empirical formula of adrenaline based on its percentage composition, we will follow these steps:

### Step 1: Assume a Sample Size
Assume the total mass of the sample is 100 grams. This simplifies calculations since the percentages can be directly converted to grams.

### Step 2: Calculate the Mass of Each Element
Using the assumed mass of 100 grams, we can calculate the mass of each element in the compound:
- Mass of Carbon (C) = 56.8% of 100 g = 56.8 g
