direct relationship
so divide
temperature constant
decrease volume
increase pressure
inverse relationship
pressure constant
r=ratio
n= number of moles
Ideal Gas Law
PxV=nRT
R=0.08205 L atom / mol x K
= 8.3145 L kPa / mol x K
= 8.3145 J / mol x K
1.987 cal / mol x K
= 62.364 L torr/ mol x K
R = .0821 atm
R= 8.31 kPa
R= 62.4 torrs
Notes: 1 atm= 101.32 atm
1 J= 1 L kPa
1 cal= 4.182 J
1 atm= 760 torr
What pressure will be exerted by .450 mol of gas at 25C if it is contained
in a .650L vessel?
Px.650L= .450mol(.0821)(25 298K)
Px.650L=11.00961
=16.92307692
=17.0 atm
