How many liters of liquid nitrogen are produced when 360.0 L of nitrogen gas is liquified at 77.36 kl

Answer 1

I don't see a pressure or a density.
Use PV = nRT assuming you have a pressure somewhere and solve for = number of mols.
Then find the density of liquid N2 at that temperature (I don't know what K| stands for) and use volume = mass/density.
