5. Determine the freezing point of a 0.97 m solution of naphthalene dissolved in benzene. Pure benzene has a freezing point of 5.50C and a freezing point depression constant of 4.90C/m. a) 0.74C b) 1.33C c) 4.17C d) 4.76C e) 1.68C 6. Choose the aqueous solution that has the highest boiling point. These are all solutions of nonvolatile solutes and you should assume ideal van't Hoff factors where applicable. a) 0.100 m NaCl b) 0.100 m CsHO) (a nonelectrolyte) c) 0.100 m NaNO, d) 0.100 m Li2SO4 e) They all have the same boiling point
