Question

A mixture of gases in a 5.0 L container has a total pressure of 616 mmhg. Given the nitrogen is one of the gases and is about 84.2% of the mixture what is it’s partial pressure?

Answer 1

In order to find out the partial pressure of Nitrogen in this container, we have that the total pressure is 616 mmHg, and Nitrogen is 84.2% of this total pressure, and the total pressure is just the sum of all the partial pressures in a container, therefore if 616 mmHg is 100% of the pressure, therefore Nitrogen will be:

100% = 616 mmHg

84.2% = x mmHg

100x = 616 * 84.2

x = 519 mmHg is the partial pressure of Nitrogen in this container
