How is the mole fraction of a component defined?

Options

  1. ANumber of moles of the component divided by the total mass of the solution
  2. BNumber of moles of the component divided by the volume of the solution
  3. CNumber of moles of the component divided by the total number of moles of all the components
  4. DNumber of moles of the component divided by the density of the solution

Correct answer

C. Number of moles of the component divided by the total number of moles of all the components

Step-by-step solution

The paragraph provides the definition of mole fraction as the number of moles of the component divided by the total number of moles of all the components.
