Answer in General Chemistry for lyndsey #169375
A gas mixture containing oxygen, nitrogen, and helium exerts a total pressure of 925 torr .
If the partial pressures are oxygen 445 torr and helium 50 torr, what is the partial pressure (torr) of the nitrogen in the mixture?
PTotal=925 torr , PO = 445 torr , PHe = 50 torr
PTotal = PO + PHe + PN
PN = PTotal – PO – PHe
PN = 925 – 445 – 50
PN = 430 torr
