Answer:
∆S = ∆H / T = 17.2 kJ/mol (298 K)
∆S = 0.0577 kJ/mol K
∆S = 0.0577 kJ/mol K x 1.41 moles = 0.0814 kJ/K = 81.4 J/K
1.41 mol x 17.2 kJ/mol = 24.25 kJ
∆S = 24.25 kJ / 298 K = 0.0814 kJ/K = 81.4 J/K

The total mass of the protons is 1.338 * 10^-23 g
<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
