Homework Statement
A 3-ft^3 container is filled with 2-lbm of oxygen at a pressure of 80 psia. What is the temperature of the oxygen?
Homework Equations
pV= nRT
T= PV/nR
R= 10.7316 psia x ft^3/ lbmol x R
The Attempt at a Solution
Hi everyone! So I understand how to use the Ideal Gas Law but my answer doesn't seem right so I think I might have messed up a conversion somewhere?
T= ?
V= 3 ft^3
n= 2 lbsm
R= 10.7316 psia x ft^3/ lbmol x R
P= 80 psia
Using T= PV/nR
T= (80 psia)(3 ft^3)/(2 lbsm)(10.7316 psia x ft^3/ lbmol x R)
I was able to cancel out the psia, ft^3, lbmoles, and was left with R which I am assuming means my temperature in Rankine? After calculating the above I got:
T= 240/21.46= 11.18 R
Can anyone let me know if I did this correctly? Thank you so much in advance.
