I don't have my data booklet handy but this question seems like it can be solved by manipulating the formula PV=nRT

So I would convert. 800 atm into Kpa, then turn - 19 to Kelvin by adding 273 which gives you. R is a constant represented by 8.314 and n is the moles that you have which is 4.50

when you manipulate the formula you can put it a V=nRT:P

plug in 4.50 for n, 8.314 for R and 254 for T (what your temperature is in Kelvin)

change your atm to Kpa and you can solve for volume ...

P. S this is the ideal gas law so all units should be put in in their proper form, IE; Volume in litres, "n" in moles, R as 8.314, Temperature in Kelvin, and P in KPA
