FREE Expert Solution

We're being asked to determine the mole fraction of methanol in a mixture of water and methanol.

Recall that mole fraction can be calculated as:

mole fraction CH3OH=mole CH3OHtotal moles

Hence we have to calculate for moles of CH3OH and water using the mass and molar mass provided
