A gas mixture, with a total pressure of 300. torr, consists of equal masses of Ne (atomic weight 20.) and Ar (atomic weight 40.). What is the partial pressure of Ar, in torr

The partial pressure will be "100 torr".

Explanation:

Given:

By assuming Ar and Ne having 50 gm each, we get

mol of Ne =

                =

mol of Ar =

               =

now,

then,

hence,

The partial pressure of Ar will be:

⇒

By substituting the values, we get

i think its 5049.

i hope this !
