~~~~~~~~~~~~~~ 

Use two rules when solve such problems:


    (1)  Total pressure of a mixture of gases is the sum of partial pressures.


    (2)  Partial pressure of a gas in the mixture is proportional to its molar mass in the mixture.


It gives you, for your problem


     =  = 0.4713 atm  (rounded).    ANSWER


     =  = 1.8287 atm  (rounded).    ANSWER

Solved and thoroughly explained.
