Question

A solution is made by mixing equal masses of methanol, CH4O, and ethanol, C2H6O. Determine the mole fraction of each component to at least three significant figures.

Answer 1

Assume you're using 10 grams of each and convert them to moles.

then use the formula below to find the mole fraction (\(\chi_a\)) of each species:

\(\large \chi_{ethanol}=\dfrac{n_{ethanol}}{n_{CH_4O}+n_{ethanol}+n_{C_2H_6O}}\)

Do this for each one of them.

n= moles
