A gas cylinder contains only the gases radon,nitrogen,and helium.The radon has a pressure of 222 torr while the nitrogen has a pressure of 446 torr.If the total pressure inside the cylinder is 771 torr,what is the pressure that is due to the helium?

Question

Quizplus · Accepted Answer

To find the pressure that is due to the helium, we can use the fact that the total pressure inside the cylinder is the sum of the partial pressures of each gas. That is,

Total pressure = pressure of radon + pressure of nitrogen + pressure of helium

Substituting the given values, we have:

771 torr = 222 torr (radon) + 446 torr (nitrogen) + pressure of helium

Solving for the pressure of helium, we get:

Pressure of helium = 771 torr - 222 torr - 446 torr 
Pressure of helium = 103 torr

Therefore, the pressure that is due to the helium is 103 torr, which is option D.
