Question

A gas mixture containing O2 N2 and He exerts a total pressure of 1256 torr. If the partial pressures are 555 torr for O2 and 143 torr for He, what is the partial pressure in atm of the nitrogen in the mixture?

Answer #1

1. A gas mixture containing oxygen, nitrogen, and helium exerts
a total pressure of 950 torr . If the partial pressures are oxygen
425 torr and helium 40 torr , what is the partial pressure (torr)
