Diluting sulfuric acid with water is highly exothermic:
(Use data from the Appendix to find 
for diluting 1.00 mol of H2SO4(l)
(d = 1.83 g/mL) to 1 L of 1.00
MH2SO4(aq) (d =
1.060 g/mL). )
Suppose you carry out the dilution in a calorimeter. The initial
T is 22.8°C, and the specific heat capacity of the final
solution is 3.334 J/g
K.
What is the final T in °C ?

You should use care when dissolving H_2SO_4 in water because the process is highly exothermic. To measure the enthalpy change, 4.5 g of concentrated H_2SO_4 (l) was added (with stirring) to 148 g of water in a coffee-cup calorimeter. This resulted in an increase in temperature from 20.8 degree C to 27.7 degree C. Calculate the enthalpy change for the process H_2SO_4 (l) rightarrow H_2SO_4(aq), in kJ/mol. Assume the specific heat capacity of the solution is 4.2 J/g K. Enthalpy...
