Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I have what should be an easy problem, but I, of course, am having some issues.

Here's the problem: The temperature of 2 moles if an ideal gas is 380 K. How much work does the gas do in expanding isothermally to 3 times its initial volume?

So I know I'm gonna to need to use this equation to find the work done:

[itex]W = nRT ln (\frac{V_f}{V_i})[/itex]

I know that:

n = 2

R = 8.31

T = 380

Vi = (3)Vi

Vf = ?

I'm hung up on the volume portion of this problem. I don't have an initial or final volume and that's what I can't seem to work around. Any help would be greatly appreciated.

Thanks in advance.
