n = 120 kPa x 0.274 L
--------------------------
8.31 kPa x L x mol -1 x K -1 x 348 K
When I go to work out this part of the equation to get to the final answer, I am not sure if I am subing the correct numbers because I dont' come out with the correct answer
So kPa = 101.3
L= 22.4
mol -1 = 1 ?
K -1 1/273 ?
Are these the correct substitutions?
