The partial pressure of N2 after mixing is 600 torr. The partial pressure of N2 after mixing gases can be calculated using Dalton's Law of Partial Pressures. This law states that the total pressure of a mixture of non-reacting gases is the sum of the partial pressures of individual gases.
Dalton's Law is expressed as
where
is the total pressure, and
are the partial pressures of individual gases.
Suppose the gases involved are N2 and O2. If the partial pressure of O2 is given as 200 torr, and the total pressure is 800 torr, the partial pressure of N2 can be calculated as follows:
800torr−200torr
600torr
Therefore, the partial pressure of N2 after mixing is 600 torr.
This calculation follows Dalton's Law, emphasizing that each gas in a mixture contributes to the total pressure according to its partial pressure. In this scenario, the partial pressure of N2 is determined by subtracting the partial pressure of O2 from the total pressure of the gas mixture.
