UNIT 3.4 IDEAL GAS LAW

Chemistry is the study of matter and interactions. Chemistry overlaps with many other sciences.

Below is the contents for this sub unit.

IDEAL GAS LAW

Review Gas Laws

Ideal Gas Law:

PV = nRT

P - pressure

V - volume

n - mole

R - Gas Constant = 0.08206 L atm / mol K = 8.145 L Pa/ mol K

T = Temperature

In mixture of ideal gases:

Partial pressure: P(a) = P(total) x X(a)

Mol fraction: X(a) = mol(a) / total mol

P(total) = P(a) + P(b) + ...

The total pressure is the sum of all the individual pressures

Be able to read graphical representations of P, V, T, and n to describe gas behavior
