It is a bigger molecule than C2H6.
Explanation:
Transfer of mass A into stagnant film B depends on the availability of driving force.
Whereas driving force is the pressure difference at the surface of A and the bulk.
As, 

Therefore, putting the given values into the above formula as follows.

= 
= 0.132 
Thus, we can conclude that the flux of A from a surface into a mixture of A and B is 0.132
