Question

If two gases are present in a container, the total pressure in the container is equal to

Answer 1

Answer: sum of the pressure of the two gases present.

Explanation:

According to Dalton's law, the total pressure of a mixture of gases is the sum of individual pressures exerted by the constituent gases.

$p_{total}=p_A+p_B$

For example if there are there are two gases hydrogen and oxygen with individual pressure of 30 and 20 atm each. Then the total pressure in the container will be:

$p_{total}=p_{H_2}+p_{O_2}$

Thus $p_{total|=30atm+20atm$

$p_{total}=50atm$

Thus if two gases are present in a container, the total pressure in the container is equal to sum of the pressure of the two gases present.
