Answer to Question #95559 in General Chemistry for hunter

Question #95559
When 0.650 g of solid zinc is added to 50.0 mL of 2.00 M HCl in a Styrofoam cup calorimeter, the temperature of the solution increased from 22.4 °C to 32.9 °C. Calculate the molar enthalpy change (in kJ/mol) for this reaction? Assume that the density of the aqueous HCl solution is = 1.00 g/mL and the specific heat capacity of solution = 4.19 J/(g·°C)
