Atoms are the smallest division of the element. The potassium atoms present in the 235 gm of the compound is atoms.
Given,
Calculate the number of moles as:
In the given compound , there are two atoms of potassium and one atom of sulphur.
If, 1 mole = atoms of potassium
Then, 2.13 moles = X atoms
Solving for X:
Therefore, option c. is correct.

Explanation:
Entropy means the amount of randomness present within the molecules of the body of a substance.
Relation between entropy and microstate is as follows.
S =
where, S = entropy
= Boltzmann constant
= number of microstates
This equation only holds good when the system is neither losing or gaining energy. And, in the given situation we assume that the system is neither gaining or losing energy.
Also, let us assume that = 1, and
= 0.833
Therefore, change in entropy will be calculated as follows.
=
=
=
or, =
Thus, we can conclude that the entropy change for a particle in the given system is J/K particle.
