I want to find the number of moles and I have the ideal gas equation as :

n = PV/RT

However I think I'm using the wrong units to find it, I want the answers in moles.

n = (1 Pa * 1 m^3) /(8.314 JK^-1 mol^-1 * 1K)

so would this give the answer x mol^-1??

I can't see how that would be.

Thanks.

Where's the mol^-1 in the formula? What's

[tex]\frac{1}{a^{-1}} = ?[/tex]

Doesn't that just equal a? Not sure how that helps?

Isn't 1Pa * 1m^3 = 1 Pa m^3??

n gives the number of moles and you are using the right units.
