We’re being asked to determine the mole fraction of CH3OH in an aqueous solution that is 12.0 m in CH3OH


Recall that molality is the ratio of the moles of solute and the mass of solvent (in kilograms)


In other words:


Molality (m)=moles solutekg solvent



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

mole fraction (X)=mole of solutemole of solution


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