1 D Question 7When 1.64 g of an unknown salt, A2B3 isadded to a calorimeter containing 88 ml ofwater at25.3 °C the temperature change is 2.81 °C. In asubsequent experiment the molar mass of saltAB is determined to be 27.4 g/mole.Determine the molar enthalpy.molefor the reaction.Assume the salt completely ionizes in water,that the density of the solution is 1.0 g/ml andthat the specific heat of the solution is thesame as that for water 4.18 J/(g°C) A 9.45g piece of an unknown metal at 470.8 °Cis placed into a coffee cup calorimetercontaining 84.6g of water at 8.7 °C. After themetal is added to the water the temperature ofthe water climbs to 13.2 °C. What is thespecific heat of the metal in J/(g°C)?Note: the specific heat of water is 4.18 J/(g®C).
