Question

Consider the dissolution of CaCl₂:
CaCl₂ (s)→ Ca²+ (aq) + 2Cl(aq) ΔH = -81.5 kJ
An 11.7-g sample of CaCl2 is dissolved in 126 g water, with both substances at 24.2°C. Calculate the final temperature of the solution assuming no heat loss to
the surroundings and assuming the solution has a specific heat capacity of 4.18 J/°C-g.
Temperature:
°℃
