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 ?

partial pressure is directly related to mole fraction.
partial pressure of Kr = 6.71.62.8
molefractionKr=partialpressureKr/6.7atm 
Thats what I did! THANK YOU!
