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 = [tex]n_1=1 mol[/tex]
Moles of water = [tex]n_2=4 mol[/tex]
Mole fraction of ethylene glycol = [tex]\chi_1=\frac{n_1}{n_1+n_2}[/tex]
[tex]\chi_1=\frac{1 mol}{1 mol+4 mol}=0.2 [/tex]
Mole fraction of water = [tex]\chi_2=\frac{n_2}{n_1+n_2}[/tex]
[tex]\chi_2=\frac{4 mol}{1 mol+4 mol}=0.8 [/tex]
