Answer:

Approx. #25-30*mol#

Explanation:

From the Ideal gas equation............

#n=(PV)/(RT)=(18.4*atmxx50.0*L)/(0.0821*L*atm*K^-1*mol^-1xx400*K)=#

#??"moles"#. What mass does this represent?

I really would speak to the caretaker, if he is letting compressed gas cylinders get that hot.......he deserves a beat-down.
