1) A student determines the molar mass of acetone,CH3COCH3, by the method used in thisexperiment. She found that the equilibrium temperature of amixture of ice and water was 1.0oC on herthermometer. When she added 11.1g of her sample to themixture, the temperature, after thorough stirring, fell to-3.0oC. She then poured off the solution through ascreen into a beaker. The mass of the solution was90.4g.
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 asshe had in her experiment?
f. What did she find to be the molar mass of acetone,assuming she made the calculation properly?
