A 5.46 L cylinder contains 2.35 mol of helium gas at 7.0◦C. What is the pressure of the gas in the cylinder?

Answer 1

since PV/T = k,
you want P (in torr) such that
(P*5.46)/(7.0+273.15) = (760*2.35*22.4)/273.15

Answer 2

I got 7514.952712, is that correct?

Answer 3

7514.952712 what? lbs? tons? kilopascals?

Answer 4

I solved for P and got 7514.952712 torr.
