A student weighs out 0.975 g of magnesium oxide (MgO, MM = 40.31 g/mol) and adds it to a constant pressure calorimeter containing 100.0 mL of 0.600 M HCl at 22.1°C. After the reaction stopped, the temperature of the solution inside the calorimeter was 25.2°C. Calculate the ∆H (in kJ) for the reaction. Assume the specific heat of the solution is 4.18 J/g°C and the density of the solution is 1.00 g/ml. MgO (s) + HCl (aq) → MgCl2 (aq)...
