(R=0.082 L atm mol-1 K-1)


21 g Nitrogen gas at which gas occupies 164 mL at 6 atm.


PV = n RT


whereby:

P = presure


V = volume


n = number of moles


R = gas constant ( 0.082 L atm mol- 1 K-1)


T = temperature


Therefore :

Nitrogen gas = 14g

[(21)(1000)] / (14) = 1500cm3


T = (PV) / (n R)

T = [(6)(1500) ] / [ ( 0.082)(164)]

= (9000) / (13.448)


T = 669.244k
