When 50.4 mL of 0.28 M AgNO3 and 20.8 mL of 0.28 M NaCI, both at 25.26°C, are mixed in a coffee-cup calorimeter, AgCl precipitates and the temperature of the mixture increases to 31.25°C. Calculate A H in kJ/mole of AgCl (s) produced during the reaction. (Assume that the total volume is the sum of the volumes and that the density and specific heat capacity of the solution are the same as for water: d 1.00 g/mL and c = 4.18 J/g°C). Enter AH in kJ/mol to 1 decimal place and without units.
5.21 g of MgSO₄ is placed into 100.0 mL of water. The water's temperature increases by 6.70°C. Calculate ∆H, in kJ/mol, for the dissolution of MgSO₄. (The specific heat of water is 4.18 J/g･°C and the density of the water is 1.00 g/mL). You can assume that the specific heat of the solution is the same as that of water.
