Solution: Consider the apparatus shown in the drawing.What is the partial pressure of N2 after mixing?

Solution: Consider the apparatus shown in the drawing.What is the partial pressure of N2 after mixing?

Problem

Consider the apparatus shown in the drawingTwo gas flasks are connected by a tube with a stopcock in the middle. N2 is in the flask on the left (2.0 liters, 1.0 atmospheres, 25 degrees C) and O2 is in the flask on the right (3.0 liters, 2.0 atmospheres, 25 degrees C)..

What is the partial pressure of N2 after mixing?

Solution

We have to determine the partial pressure of nitrogen gas when the gases are mixed in the shown apparatus.


Partial pressure of a gas is the pressure of a gas component in the mixture which it would have if it occupied the whole volume alone.

When the two gases are mixed, the total volume of the mixture is the sum of individual gas bulbs.
