A student determines the molar mass of acetone by the method used in this experiment. She found that the equilibrium temperature of a mixture of ice and water was 0.5 C on her thermometer. When she added 10.5 g of her sample to the mixture, the temperature fell to -3.7 C. She then poured off the solution through a screen into a beaker. The mass of the solution was 86.4 g. How much acetone was in the decanted solution?
