a student determines the molar mass of acetone CH3COCH3 by the method used in this experiment. she found that the equilibrium temperature of a mixture of ice and water was 10c oh her thermometer. when she added 11.1g of her sample to the mixture the temperature after thorough stirring fell to -3.0c. she then poured off the solution through a screen into a beaker. the mass of the solution was 90.4g. what was the freezing point?. what was the molarity of the acetone how much acetone was in the decand solution how much water was in the decand solution how much acetone would there be in a solution containing 1kg of water and acetone at the same concentration as she had in her experiment what did she find to be the molar mass of acetone assumming she made the calculatuion properly?
