PV=nRT
solve for P change temp to K,
as a check, at STP you would have for 1.4 mols, (22.4*1.4)=about 30 liters
that is at temp 273K, your temp is (-170+273=about 100K) so you should have then 30*/2.7 liters or 12 liters about at standard pressure. But you have 2.7liters, so pressure= 12/2.7 =about 4 atmospheres
so do your calc, and it should be about 4 atm.
1.4 mol of gas at a temperature of -170 degreed celcius fills a 2.9 L container.
what is the gas pressure?
