Question

If 0.6 is the mole fraction of solute in a Solution, then the mole fraction of solvent would be.
a) 0:1
b) 0.2
c) 0.3
d) 0.4​

Answer 1

Answer:

         d) 0.4​

Explanation:

mole fraction of solute + mole fraction of solvent = 1

0.6 + mole fraction of solvent = 1

mole fraction of solvent = 1 - 0.6

mole fraction of solvent = 0.4

Answer 2

Concept:

The number of moles of a particular component in the solution divided by the overall number of moles in the sample solution is known as the mole fraction.

Given:

Mole fraction of solute = 0.6

Find:

Calculate the mole fraction of the solvent?

Solution:

The mole fraction can be calculated as:

              Mole fraction of solute + mole fraction of solvent = 1

The mole fraction of the solvent can be calculated as:

             Mole fraction of solvent = 1 - mole fraction of solute = 1 - 0.6

             Mole fraction of solvent = 0.4

Thus, the mole fraction of the solvent is 0.4.

If 0.6 is the mole fraction of solute in a solution, then the mole fraction of solvent would be 0.4.

Hence, the correct option is (d) 0.4.
