0.10 mol of argon gas is admitted to an evacuated
Chapter 16, Problem 29E(choose chapter or problem)
\(0.10 \mathrm{~mol}\) of argon gas is admitted to an evacuated \(50 \mathrm{~cm}^{3}\) container at \(20^{\circ} \mathrm{C}\). The gas then undergoes an isothermal expansion to a volume of \(200 \mathrm{~cm}^{3}\).
a. What is the final pressure of the gas?
b. Show the process on a \(p V\) diagram. Include a proper scale on both axes.

ANSWER:
Step 1 of 2
Part a
From the data given, we are required to calculate the final pressure of the gas.
Given:
The number of moles of argon mol
The initial volume =
Temperature °C = 293 K
The universal gas constant is J/mol K
The initial pressure can be calculated as,
Pa
Pa
From the equation
Pa
