A A student determined the molar mass of an unknown non-dissociating liquid by the method described in this experiment. She found that the equilibrium temperature of a mixture of ice and pure water was indicated to be +0.4°C on her thermometer. When she added 9.9 g of her sample to the mixture, the temperature, after thorough stirring, fell to -3.7°C. She then poured off the solution through a screen into a beaker. The mass of the solution was 84.2 g. a. What was the freezing point depression? °C b. What was the molality of the unknown liquid? m c. What mass of unknown liquid was in the decanted solution? d. What mass of water was in the decanted solution? 4G 72% 4:37 = bartleby Q&A Science / Chemistry / Chemic... / 11th Ed... : A student determined the molar m... D c. What mass of unknown liquid was in the decanted solution? d. What mass of water was in the decanted solution? e. How much unknown liquid would there be in a solution containing 1 kg of water, with her unknown liquid at the same concentration as she had in her experiment? g unknown liquid f. Based on these data, what value did she calculate for the molar mass of her unknown liquid, assuming she carried out the calculation correctly? g/mol This textbook solution is under construction.
