Step 1
In this case, the numerator is 40% (4/10) methanol, 409 ethanol, and 20% (2/10) water by mass. The denominator is 100% (100/120). Show more…

Calculate the mole fractions of methanol, $\mathrm{CH}_{3} \mathrm{OH} ;$ ethanol, $\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH} ;$ and water in a solution that is $40 \%$ methanol, 40\% ethanol, and 20\% water by mass. (Assume the data are good to two significant figures.)
Adi S.
Find the mole fraction of methanol CH3OH and water in a solution prepared by dissolving 4.5g of alcohol in 40g of H2O. The molar mass of H2O is 18g/mol and the molar mass of CH3OH is 32g/mol.
Ma Ednelyn L.
Calculate the mole fractions of ethanol and water in a solution that is made up of $20.0$ grams of ethanol, $\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{OH}$, and $80.0$ grams of water.
