A 5.30M solution of HCl (500mL) is placed in a coffee-cup calorimeter containing 50.0g in ice cubes. A 50.0g-piece of manganese is dropped into the calorimeter. After the reaction, the temperature of the mixture has risen from 0.0°C to 20.4°C. [∆fusH = 333J/g; ∆vapH= 2260J/g]

a) Assuming the solution has a specific heat capacity of 4.184J/gK and a density of 1.00g/mL and the calorimeter does not absorb any heat, calculate the heat (in J) involved in this reaction.

b) What is the ∆H per mole of gas produced for this reaction?

In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat capacity of a solid, or to measure the enthalpy of a solution phase reaction.   Since the cup itself can absorb energy, a separate experiment is needed to determine the heat capacity of the calorimeter. This is known as calibrating the calorimeter and the value determined is called the calorimeter constant.   One way to do this is to use a common metal...
