7. IDEAL GAS LAW 11.3 PPT

8. Ideal Gas Law
The ideal Gas Law shows the mathematical relationship among pressure, volume, moles, and temperature of gases.
R is the universal gas constant, that is derived from the equation.
PV=nRT 
Number of moles

9. Universal Gas Constant
The value of R depends on whether pressure is given in units of atm or kPa
R= Latm/molK
R=8.315 dm3kPa/molK

10. Ideal Gas Law P = ? atm PV = nRT n = 0.412 mol T = 16°C = 289 K
Calculate the pressure in atmospheres of mol of He at 16°C & occupying L.
GIVEN:
P = ? atm
n = mol
T = 16°C = 289 K
V = 3.25 L
R = Latm/molK
WORK:
PV = nRT
P(3.25)=(0.412)(0.0821)(289)
L mol Latm/molK K
P = 3.01 atm
