A student poured 100 ml of water (density = 1.00 g / mL) into a coffee calorimeter, noted that the temperature of the water was 18.8oC, then added 5.33 g KOH. With the lid on, the mixture was stirred, temperature increased and the maximum temperature reached at the time of mixing 31.6 oC.
Calculate the heat of the system in this dissolution reaction (qsys). (
Approximate the specific heat capacity, cp as 4.18 J g-1 K-1.
Do not consider the contribution to the heat generated from the calorimeter; assume that this is zero. Only calculate the heat from the heat capacity of the solution.
make sure you consider the sign of qsys
qsys for dissolution of KOH = J
