Answer #1

Dalton's Law of partial pressure.

''This law states that the total pressure exerted by the mixture of non reacting gases is equal to the sum of the partial pressures of individual gases''

That means

Let in a container there are two gases and have their partial pressure respectively.

The total Volume of the mixture is V

We know the idle gas equation that

Applying above concept,

Where are the number of moles of respectively.

As per the Dalton's Law of partial pressure

Hence

Example

Let a 2L of container is pressurized with 0.25 atm pressure of N2 gas and 0.75 atm of O2 gas,then the total pressure is

Hence the total presure of the container is 1 atm
