Ammonia contains `82.35%` of nitrogen and `17.65%` of hydrogen. Water contains `88.90%` of oxygen and `11.10%` of hydrogen. Nitrogen trioxide contains `63.15%` of oxygen and `36.85%` of nitrogen. Show that these data illustrate the law of receprocal proportions.

Explanation

To illustrate the law of reciprocal proportions using the given data, we will follow these steps:

### Step 1: Understand the Law of Reciprocal Proportions
The law of reciprocal proportions states that if two elements combine separately with a fixed mass of a third element, the masses of the two elements that combine with the fixed mass are in a simple ratio to each other.

### Step 2: Identify the Elements and Their Percentages
From the question, we have:
1. **Ammonia (NH₃)**:
