Suppose that 50.0 mL of a 0.250 M HCl solution is mixed with 50.0 mL of a 0.100 M

Question

Ba(OH)2 solution in a coffee-cup calorimeter. The temperature of the resulting solution increases by
1.76 oC . Calculate DH for the reaction between HCl (aq) and Ba(OH)2 (aq) in kJ per mole of Ba(OH)2 reacted. Assume that the specific heat capacity of the resulting solution is 4.18 J/g oC and
that the density of the resulting solution is 1.00 g/mL . Also assume that the heat capacity of the
calorimeter itself can be ignored.

Answer 1

If you expect to continue getting help you should show some work. Or something about how you would attack the problem. Or EXACTLY what you don't understand about the process.

Answer 2

q = [mass H2O x specific heat H2O x delta T]
Then dH is q/mol Ba(OH)2 and convert to kJ.
