1. clhorine gas occupies a volume of 1.2l at 720 temperature. what volume will it occupy at 760 torr??
2. hydrogen gas was cooled from 150'C to 50'C. its new volume is 75ml. what was its original volume?
3. flourine gas exerts as pressure of 900 torr. when the pressure is changed to 720 torr, its volume is 250ml. what was the original volume?

pV=nRT
p= pressure (in torr)
V = volume in (in L)
n= number of moles (in mol)
R = Gas constant (in L Torr K^[-1] mol^[-1]) = 6.23637 L Torr K^[-1] mol[-1]
T = Temperature (in K)
