4) Mixtures of He and oxygen are used in scuba diving to help prevent “TheBends". For a particular dive the total pressure in the tank is 15 atm. If thepartial pressure of oxygen is 6.0 atm, what is the partial pressure of He ?A

Relax

Respuesta :

By following Daltons laws of partial pressure .

" the pressure that eachgaswould have exerted ,Add up to the total pressure" .

• Therefore :

,

• Total Pressure = P.Pressure (oxygen) + P.Pressure of (He)

15 atm = 6atm + Pressure of He

P.Pressure ofHe = 15atm-6atm

= 9 atm

This means that the partial pressure of He = 9atm +
