dairn · Answer

Using the equation

$$PV = nRT$$
I got 0.63 moles, C. Is this correct?

aaronq · Answer

If you converted the temp to Kelvin and used the appropriate gas constant (R), then it should be.

dairn · Answer

I have a feeling I didn't get the correct answer as I'm not entirely sure how to get R.
