We’re being asked to calculate for the mole fraction of caffeine (C8H10N4O2in the solution.

The solution is made up of caffeine (C8H10N4O2) and chloroform (CHCl3) with a concentration of 0.0510 m. Since chloroform is the solvent, we can say that caffeine is the solute.

Mole Fraction (X) relates the moles of solute and solvent within a solution:

We’ll calculate the mole fraction of caffeine using the following steps:
