Q2:

Solution properties: properties that represent the solution as a whole mixture.

Partial properties: properties belong to the species that exist in the solution.Pure species properties: properties of the individual species as they exist in the pure state without

the presence of other species at the same  P  and T  of the solution.

Q1

Xi=yi/Ki

0.578/10=0.05

0.1083/2.05=0
