A student determines the molar mass of acetone CH3COCH3, by themethod used in this experiment. She found that theequilibrium temperature of a mixture of ice and water was 1.0degrees C on her thermometer. When she added 11.1g of hersample to the mixture, the temperature, after thorough stirring,fell to -3.0 degrees C. She then Poured off the solutionthrough a screen into a beaker. The mass of the solution was90.4 degrees C.
a. What was the freezing point depression?
b. What was the molality of the acetone?
c. How much acetone was in the decanted solution?
d. How much water was in the decanted solution?
e. How much acetone would there be in a solution containing 1kg of water and acetone at the same concentration as she had in herexperiment?
f. What did she find to be the molar mass of acetone, assumingshe made the calculation properly?
