Answer:

Mole fraction of water is 0.8.

Explanation:

Mole fraction is defined as ratio of moles of single component to the sum of moles of all components present in the solution.

Moles of ethylene glycol = n_1=1 mol

Moles of water = n_2=4 mol

Mole fraction of ethylene glycol = \chi_1=\frac{n_1}{n_1+n_2}

\chi_1=\frac{1 mol}{1 mol+4 mol}=0.2

Mole fraction of water  = \chi_2=\frac{n_2}{n_1+n_2}

\chi_2=\frac{4 mol}{1 mol+4 mol}=0.8
