### Homework Question 9.9

Posted:

**Fri Feb 09, 2018 10:08 pm**Hi!

How come in question 9.9 you use just R instead of 3/2R when determining the change in entropy?

The question is: Calculate the entropy change associated with the isothermal expansion of 5.25 mol of ideal gas atoms from 24.252 L to 34.058 L.

Thanks!
