## What is Daltons Law?

In Chemistry, The pressure of the gas mixture is equal to the sum of the pressure of partial gases in a container is called daltons partial pressures law.

Partial Pressure of a gas:

When the gases are present in the container, the unsafe movement of their molecules exerts pressure on the walls of the container. If we have mixture of gases in a container then the pressure applied by individual gas is partial pressure of gas. Units of a pressure is kilopascal.

Formula of Daltons Law:

Ptotal = P1 + P2 + … + Pn

Pressure of individual gas can be calculated by the formula,

P = n*R*T/v

Where,

v is the volume.

R = 8.314 Jk-1mol-1, ideal gas constant.

T is the temperature.

n is the no.of moles.

### How to Calculate the Partial Pressure of the Gas?

To calculate the partial pressure of the gas you need to go through the guidelines that are given below. Take a quick tour carefully.

• Note down the values that was given in the problem.
• Apply the formula of ideal gas.
• Substitute the values in it and simplify it.
• Finally get the result.

Example:

Question: Calculate the pressure of the gas if a gas container has 4L of helium gas. The temperature of container is 180K. And there are 4 moles of helium present in the container.

Solution:

Given values are:

Temperature(t) = 180k

Volume (v) = 4L

No. of Moles(n)= 4 moles

Now, apply the pressure of the gas formula.

P = [n*R*T]/v

= [4*8.314* 180] / 4, As we know that R = 8.314 Jk-1mol-1

=1496.52 Kpa(Kilopascal)

Hence the pressure of the gas is 1496.52 Kpa.
