<h3>What is a proton?</h3>
A proton is the positively charged particle in an atom. It is found in the nucleus along with the neutrons and are collectively called the nucleons.
The hydrogen atom has only one proton while the nitrogen atom has seven protons. Thus makes a total of eight protons in the ammonia molecule.
Hence, the total mass of protons in the ammonia molecule =
8 ( 1.673 × 10^-24 g) = 1.338 * 10^-23 g

Answer:
The options to this question are incomplete. The remaining two options are:
C. Water expands and becomes less dense when it freezes.
D. Water contracts and becomes less dense when it freezes.
The answer is C. Water expands and becomes less dense when it freezes.
Explanation:
Water is a chemical compound that exists in the three states of matter viz: solid as ICE, gas as vapour and liquid as WATER. However, due to the DENSITY properties of each state, ice floats on water. Ice is less dense than water.
When liquid water freezes, it's particles expands i.e increases in volume. Hence, it becomes less dense than water. This causes an iceberg to float on water because it has a lesser density compared to the liquid water caused by an expansion of its particles.
