The ideal gas law, PV = nRT is independent of
the kind of gas. In other words, the pressure exerted
by a given number of ideal gas particles is the same
whether the sample consists of all one type of
particle or a mixture of different kinds of particles.

Therefore, the pressure exerted by a mixture of
gases can be expressed as follows:
Protal
Thota RT
V
V
A partial pressure is the pressure exerted by just one
type of gas in a mixture. A partial pressure is
calculated using only the number of moles of that
particular gas, instead of the total number of moles:
P = "KT

The sum of the partial pressures is equal to the total
pressure in the mixture:
