A 1.141 g sample of a magnesium was immersed into the coffee cup calorimeter containing 100.0 mL of 6.0 M HCl described in question 2. The equation for this reaction is the following:

 

 

Mg(s) + 2H+ (aq) ----> Mg^2+(aq) + H2 (g)

 

 

The temperature increase was extrapolated from a graph of data to be from 18.2 to 23.9 C.

 

 

Calculate the enthalpy of formation of Mg^2+(aq) in J/mol

 

-----------------

 

question 2

 

What will be the heat capacity (in units of J/K) of a constant pressure, coffee-cup calorimter that contains 100.0 mL of 6.0 M HCl solution? The density of the solution is 1.098 g/mL, the specific heat capacity of the HCl solution is 4.10 J/g*K and the heat capacity of the empty styrofoam cups is 15 J/K
