QUESTION:
A gas mixture contains each of the following gases at the indicated partial pressures: N 2 , 215 torr; O 2 , 102 torr; and He, 117 torr. What is the total pressure of the mixture? What mass of each gas is present in a 1.35 L sample of this mixture at 25.0 C?
ANSWER:Step 1 of 3
According to Dalton’s law of partial pressures, the total pressure of a mixture of gases is equal to the sum of partial pressures of each gas. ‘P’ is the total pressure and ‘p’ is the partial pressure of individual gases.
Here, the partial pressure of each gas can be represented as;
