The specific heat of a solution is X J/g*degreesC and its density is Y g/mL. The solution was formed by combining Z mL of solution A with Z mL of solution B, with each solution initially at J degreesC. The final temperature of the combined solutions is D. The heat capacity of the calorimiter used is W J/degreesC. If the reaction used is A(aq) + B(aq) -> AB(aq), and the molarity of A and B is both U mol/L, what is the heat of reaction, heat of chemicals, and heat of solution for the formation of 1 mole of AB in solution?

Use the density to calculate mass of the solution. Volume of solution is Z mL + Z mL. So mass soln = 2Z mL x Y g/mL. I think these problems are made to confuse students and they succeed with me. I'll let you convert the velow information to the format of the problem.
q solution (rxn) = (mass x specific heat x delta T) + (calorimeter constant x delta T)

M x L = moles of reaction.
heat soln/mol AB = q/moles.
