A student determines the molar mass of acetone (CH3COH3) by the method used in the experiment. She found the equilibrium temperature of a mixture of ice and water was 0.5 degrees C on her thermometer. When she added 10.5 g of her sample to the mixture, the temperature fell to -2.6 degrees C. She then poured off the solution through a screen into a beaker. The mass of the solution was 86.4 g. Using freezing point depression, find the molar mass of acetone.
