In a mixture of gases, the greater the mole fraction of component, the greater its partial pressure is.In the mixture, neon has the greatest mole fraction. Therefore, the partial pressure of neon is the greatest.

0.50 mol(20.18 g/mol) = 10.09 g Ne
0.30 mol(39.95 g/mol) = 11.985 g Ar
0.20 mol(131.29 g/mol) = 26.258 g Xe
Because xenon has the most mass in the mixture, it will exert the greatest partial pressure.
0.30 mol(39.95 g/mol) = 11.985 g Ar
0.20 mol(131.29 g/mol) = 26.258 g Xe
Because xenon has the most mass in the mixture, it will exert the greatest partial pressure.
