13.a
Are the mass and mole fractions for a mixture ever the same?
Generally not. If the components all had the same molecular weight the mass and
mole fractions would be the same.
13.b
For a mixture how many component concentrations are needed?
A total of N-1 concentrations are needed, N equals total number of components,
whether mass or mole fractions. They must sum up to one so the last one is by
default.
13.c
Are any of the properties (P, T, v) for oxygen and nitrogen in air the same?
In any mixture under equilibrium T is the same for all components.
Each species has its own pressure equal to its partial pressure Pi.
The partial volume for a component is: vi = V/mi and V is the same for all
components so vi is not.
