Question

26. Use the example of a solution of benzene in toluene to explain what is cal ly an
ideal solution
7. What characteristic of a solution determines its colligative properties?
* The vapour pressure of ethanol (CH,OH) and 1-propanol (CH,OH) at 35°C are
100 mmHg and 37.6 mmHg, respectively. Assuming ideal behaviour, calculate the
partial vapour pressures of ethanol and 1-propanol over a solution, in which the
mole fraction of ethanol is 0.3.
A solution was made by dissolving 3.75 g of a pure non-volatile solute in 95 g of
acetone. The boiling point of pure acetone was observed to be 55.95°C, and that
of the solution was 56.50°C. If the molar boiling point elevation constant(K) of
acetone is 1.71°C kg/mol, what is the approximate molar mass of the solute?
