Answer:
8563732.58906 Pa
3992793.23326 Pa
5708.00923 J
Explanation:
V = Volume
N = Number of molecules = 
T = Temperature = 300 K
b = 
= Boltzmann constant = 
P = Pressure
We have the equation

The pressure is 8563732.58906 Pa
For isothermal expansion

The pressure is 3992793.23326 Pa
Work done is given by

The work done is 5708.00923 J
The answer is D.<span>longitudinal</span>
You just multiply these two numbers, it's 1250J
<span>47 amu is the correct answer</span>
