A mixture of Xe, Kr, and Ar has a total pressure of 6.7 atm. What is the mole fraction of Kr if the partial pressures of XE and Ar are 1.6 atm and 2.8 atm?

Did anyone get .343 ?

  • CHEMISTRY -

    partial pressure is directly related to mole fraction.

    partial pressure of Kr = 6.7-1.6-2.8

    molefractionKr=partialpressureKr/6.7atm

    Thats what I did! THANK YOU!
