The salt calcium bromide is soluble in water.
When 1.48 g of CaBr2
is dissolved in 112.00 g of water, the temperature
of the solution increases from 25.00 to
26.56 °C. Based on this observation, calculate the
enthalpy of dissolution of CaBr2 (in
kJ/mol).
Assume that the specific heat of the solution is 4.184 J/g °C and
that the heat absorbed by the calorimeter is negligible.
ΔHdissolution = kJ/mol
Hdissolution = -100.0 kJ/mol
