Through Dalton's law of partial pressure...

Explanation:

When two or more ideal gases are found in one vessel without chemical interaction, each gas will behave independently of the others. Therefore, the pressure exerted by each gas in the mixture will be equal to the pressure that gas would exert if it were the only one in the container.

Remember the formula!!

#P_T = P_A + P_B + P_C +...#
