Calculate the molar enthalpy change for the reaction below.

Use the following information to answer the next question.

Ba(NO3)2 is a barium compound that is highly soluble in water. When it is added to a solution of sodium hydroxide, a precipitate forms: Ba(NO3)2(aq) + 2NaOH(aq) à Ba(OH)2(s) + 2 NaNO3(aq)

A 40.0 mL sample of 0.100 mol/L Ba(NO3)2BaSO4(aq) is mixed with 20.0 mL of excess NaOH(aq) in calorimeter. During the reaction, there is a rise in temp by 5.00 oC. Calculate the molar enthalpy change for the above reaction.
