91.7g of HCL solution was added to the calorimeter and brought to a constant temp. Then 0.5278g of MgO was added and the Temp rose from 25.65C to 32.60C and held steady. Then 0.0185g of Mg was added and the temp again rose from 30.35C to 32.20C.

Calculate the Cp for the calorimeter?

I think im getting confused with what weight is needed for the equation ..

Is this an experiment you did? Or does the problem give the heat produced by reaction of HCl with MgO and Mg? You need to know how much heat is produced from these reactions I think.
