if air is consist 80% nitrogen & 20% oxygen,what are the partial pressure?

Well we know that Partial Pressure means the pressure that would be exerted by one of the gases in a mixture if it occupied the same volume on its own.

To calculate the partial pressures of nitrogen and oxygen in air, we need to first understand the concept of partial pressure. Partial pressure refers to the pressure exerted by each individual component of a gas mixture if it occupied the same volume alone at the same temperature as the mixture.

In this case, air is composed of 80% nitrogen and 20% oxygen.

To calculate the partial pressure of nitrogen, we need to calculate 80% of the total pressure of air. Let's assume the total pressure of air is 1 atmosphere (atm).

Partial pressure of nitrogen = 80% of 1 atm = 0.8 atm

Similarly, the partial pressure of oxygen can be calculated by multiplying the percentage of oxygen (20%) by the total pressure.

Partial pressure of oxygen = 20% of 1 atm = 0.2 atm

Therefore, the partial pressures of nitrogen and oxygen in air are 0.8 atm and 0.2 atm, respectively.
