Mole Fraction (X) relates the moles of solute and solvent within a solution:
Step 1: Moles of solute and solvent.
A solution is prepared by dissolving 20.2 mL of methanol (CH3OH) in 100.0 mL of water at 25 oC. The densities of methanol and water at this temperature are 0.782 g/mL and 1.00 g/mL, respectively. For this solution, calculate each of the following.
Mole percent of methanol
