Question

prove that sum of mole fractions of all components is equal to unity​

Answer 1

Answer:

Explanation:

Mole fraction is the number of moles of part over total moles OR

Mole fraction=

Total number of moles in solution

Number of moles of a solute

​

If for example, we take that number of moles of solute as n

1

​

 and that of solvent is n

2

​

Then, Mole fraction of solute =

n

1

​

+n

2

​

n

​

​

Mole fraction of solvent =

n

1

​

+n

2

​

n

​

​

Then, sum of mole fractions will be =

​

+n
