A mixture of Ne and He, both gases, are held in a container. If the total pressure of the system (the container) is 490 torr, and the pressure of He is 430 torr, what is the pressure of Ne?

Answer 1

Total pressure = sum of partial pressures

490 torr = 430 torr + x torr

x = 490 - 430 = 60 torr

Pressure of Ne = 60 torr
