Question

When comparing two gases to determine which one is closest to an ideal gas, which strategy is best?

Answer 1

A. Look up the van der Waals' contstants. The gas with the smaller "b" value must be more ideal

B. Calculate R. The more ideal gas is the one with an R value closest 0.08206 L • atm • mol–1 • K–1

C. Look up the van der Waals' contstants. The gas with the higher "a" value must be more ideal.

D. Calculate the molar mass of each gas. A large molar mass indicates an ideal gas.

Answer 2

I am thinking B but I am not sure

Answer 3

Well, let's discuss this. Why do you think it's "B"?

Answer 4

I haven't look over this material very much yet but it seems that R is the ideal gass constant and therefore would tell me how close to ideal a certain gass is.

Answer 5

Well, if it's a constant, that means the value doesn't change. I believe it's 8.314 j/mol? I don't really remember. Does that makes sense?

Answer 6

0.08206 L • atm • mol–1 • K–1

Answer 7

-1 means ^-1

Answer 8

But you are correct.

Answer 9

I'm not sure if it never changes or if that is the ideal constant does that make sense?
