Q1. A student determines the heat of dissolution of solid calcium bromide using a coffee-cup calorimeter of negligible heat capacity. When 1.45g of CaBr2(s) is dissolved in 103.00(g) of water, the temperature of the solution increases from 25.00 degree celcius to 26.83 degree celcius. Based on the student's observation, calculate the enthalpy of dissolution of CaBr2(s) in KJ/mol. Assume the specific heat of solution is 4.184J/gc.

Q2. An electric range burner weighing 678.0 grams is turned off after reaching a temperature of 493.0 degree celcius , and is allowed to cool down to 22.1 degree celcuis. Calculate the specific heat of the burner if all the heat evolved from the burner is used to heat 561.0 grams of water from 22.1 degree celcius to 82.2 degree celcius.
