The given question is incomplete. The complete question is as follows.
An oxygen molecule is adsorbed onto a small patch of the surface of a catalyst. It's known that the molecule is adsorbed on 1 of 36 possible sites for adsorption. Calculate the entropy of this system.
Explanation:
It is known that Boltzmann formula of entropy is as follows.
s = k ln W
where, k = Boltzmann constant
W = number of energetically equivalent possible microstates or configuration of the system
In the given case, W = 36. Now, we will put the given values into the above formula as follows.
s = k ln W
=
=
Thus, we can conclude that the entropy of this system is .
As we know that mass of the iron will remain same in solid state as well as in molten state as per mass conservation theory
Now we can say
since mass is the product of volume and density so we can say
now from above equation we have
now by solving above equation we have
so final volume after it get solidify will become 175 cm^3
