Approx. $25-30*mol$

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.
