common laboratory reaction is the neutralization of an acid with a base. When 50.0 mL of 0.200 M HCl at 25.0° C is added to 50.0 mL of 0.200 M KOH at 25.0° C in a coffee cup calorimeter, the temperature of the mixture rises to 26.4° C. What is the heat of reaction per mole of acid? Assume the mixture has a specific heat capacity of 4.18 J/(g·K) and that the densities of the reactant solutions are both 1.00 g/mL.
Mass of HCl= 50ml* 1 g/ml = 50gms ( since the density is 1 ) Mass of KOH= 50 mn*1 g/ml =50 gm Total mass =50+50 =100 g
