Asample of n2 gas occupies 2.40 l at 20°c. if the gas is in a container that can contract or expand at constant pressure, at what temperature will the n2 occupy 4.80 l?

From Charle's law the volume of a fixed mass of a gas is directly proportional to the absolute temperature at constant pressure.
Therefore';
V1/T1=V2/T2
    Where; V1 = 2.40 l, T1 = 273 +20= 293 K, V2 = 4.80, and T2= ?
 2.4/293= 4.8/T2
 T2= (4.8×293)/2.4
       = 586 K or  313° C

Well to my expert knowledge and my exquisite calculations i think the the negative ion # 412 is the key to sucess
