Question

Can y’all please help with this? :(

Answer 1

P Ar = 1.5

P Xe = 0.5

P tot = 2 atm

Further explanation

Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases

Can be formulated:

P tot = P1 + P2 + P3 ....

The partial pressure is the pressure of each gas in a mixture

3 L Argon , P = 1 atm and 1 L Xe, P=1 atm⇒assume T = 273 K

mol Argon :

`\tt n_(Ar)=(PV)/(RT)=(1* 3)/(0.082* 273)=0.134`

mol Xenon :

`\tt n_(Xe)=(1* 1)/(0.082* 273)=0.045`

`\tt P_(Ar)=(nRT)/(V)=(0.134.0.082.273)/(2)=1.5`

`\tt P_(Xe)=(nRT)/(V)=(0.045.0.082.273)/(2)=0.5`

P tot = 1.5 + 0.5 = 2 atm
