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?The temperature of a reaction was monitored with an thermometer that is reported to have precision of 0.2 K (uniform distribution). If we used this thermometer to monitor the temperature change in a particular exothermic reaction, what is expanded uncertainty (use coverage factor k = 2) in the net temperature change for the following measurements: Temperature before reaction starts = 296.2 K Temperature after reaction is finished = 305.6 K Net temperature change = 9.4 K.
