Answer
0.190, 0.81
Work Step by Step
Because the equation is asking for mole fraction, we need each of the masses of each component to moles.
To find the mole fraction of the ethanol, the solute, take the number of moles of ethanol and divide that by the sum of the moles of ethanol and water.
To find the mole fraction of water, the solvent, take the number of moles of water and divide that by the sum of the moles of ethanol and water
