A 2.09 g piece of zinc metal is added to a calorimeter containing 1.50 L of 0.600 M HCl.
This results in a reaction where zinc chloride and hydrogen gas is formed, and the
temperature of the solution increases by 0.780°C. The density of the solution is 1.00 g/mL,
and its specific heat capacity is the same as water, what is the enthalpy change, per mole of
zinc, for the reaction?
