You are about to dilute 2.00 mol of 100% sulfuric acid with enough water to produce a 30 mole% aqueous solution. the acid and water are initially at 25°c.
(a) how much heat would have to be removed to keep the final solution at 25°c?
(b) suppose the flask has a mass of 150 g, and that the heat capacity of the flask and its contents is 3.30 j/(g °c). if the flask is sufficiently insulated to be considered adiabatic, what will be the final solution temperature?
