Determine how ideal the following solutions are by calculating the mole fraction of solute in each solution, and comparing that to the expected mole fractions. All data are for 25.0째C.

(a) 14.09 weight percent of I₂ in C₆H₆, MP of I₂ is 112.9째C (sublimes), and ?_fusH = 15.27 kJ/mol

(b) 2.72 weight percent of I₂ in C₆H₁₂, MP of I₂ is 112.9째C (sublimes), and ?_fusH = 15.27 kJ/mol

(c) 20.57 weight percent of para-dichlorobenzene, C₆H₄Cl₂, in hexane, MP of C₆H₄Cl₂ is 52.7째C, and ?_fusH = 17.15 kJ/mol
