Academics

Consider the dissolution of CaCl2. CaCl2(s) --> Ca2+(aq) + 2 Cl (aq) H = - 81.5 kJ A 23.5 g sample of CaCl2 is dissolved in water, with both substances at 25.0 °C. Calculate the final temperature of the solution assuming no heat is lost to the surroundings, the final mixture has a mass of 100.0 g and the solution has a specific heat capacity of 4.18 J °C-1 g-1. The molar mass of CaCl2 = 110.98 g/mol.
