Question

a gas mixture contain the following components and partial pressure co²-75 mmHG calculate the total pressure and composition in mole fraction​

Answer 1

Answer:

Key Points

(1). The total pressure of a mixture of gases can be defined as the sum of the pressures of each individual gas: Ptotal=P1+P2+… ...

(2). The partial pressure of an individual gas is equal to the total pressure multiplied by the mole fraction of that gas.

The mole fraction of any component of a mixture is the ratio of the number of moles of that substance to the total number of moles of all substances present. In a mixture of gases, the partial pressure of each gas is the product of the total pressure and the mole fraction of that gas.

From the total pressure of a mixture of gases and its percent composition, we can calculate the partial pressure of the individual gases. Example: Dry air contains 78.08% nitrogen, 20.095% oxygen, and 0.93% argon. Calculate the partial pressure of each gas in a sample of dry air at 760 torr.

the pressure that a gas in a mixture of gases would exert if it occupied the same volume as the mixture at the same temperature.
