    When 0.678 g of Ca metal is added to 200.0 mL of 0.500 M HCl(aq), a temperature increase of 11.0C is observed. Assume the solution's final volume is 200.0 mL, the density is 1.00 g/mL, and the heat capacity is 4.184 J/gC. (Note: Pay attention to

    I know that the start of the problem is this (I think): -delta H = [(200)(4.184)(11.0)(1/1000)]/[(0.678/?)] I just don't understand what the ? should be...Thanks!
