If the intermolecular forces in a liquid<span> are small, the molecules can easily escape from the surface of the</span>liquid<span>. The </span>liquid<span> will have a high </span>vapour pressure<span>. The normal </span>boiling point<span> is the temperature in which the </span>vapour pressure of a liquid<span> becomes equal to atmospheric </span>pressure<span>.</span>
<span>Chemical formula of ammonia = NH3
As we can see there are three atoms of hydrogen in one molecule of ammonia.
So in the 200 molecule of ammonia there will be = 200*3 = 600 atoms of hydrogen.
Answer - 600 atoms of hydrogen.</span>
