Compressibility factor (Z) for N_(2)" at "-50^(@)C and 800 atm pressure is 1.95 calculate mole of N_(2) gas required to fill a gas cylinder of 100 L capacity under the given conditions.

Answer»

Solution :We have `Z=(PV)/(NRT)`
`THEREFORE" mole of "N_(2) =(PV)/(ZRT)`
`=(800xx100)/(1.95xx0.0821xx223)=2240.8`
