Which of the following is the correct definition of “Mole fraction”?

Options

  1. AMole fraction of a component is the ratio of the number of moles of the component to the total number of moles
  2. BMole fraction is the ratio of the mass of a solute to the mass of the solvent in a solution.
  3. CMole fraction is the ratio of the volume of a solute to the volume of the solvent in a solution.
  4. DMole fraction is the ratio of the concentration of a solute to the concentration of the solvent in a solution.

Correct answer

A. Mole fraction of a component is the ratio of the number of moles of the component to the total number of moles

Step-by-step solution

Correct Option is : (A) Mole fraction of a component is the ratio of the number of moles of the component to the total number of moles of all the components.
