1. The problem statement, all variables and given/known data A 10.2 g sample of CaCl2 is dissolved in 103 g of water, with both substances at 25.0°C. Calculate the final temperature of the solution assuming no heat lost to the surroundings and assuming the solution has a specific heat capacity of 4.18 J/°C·g. 2. Relevant equations Heat evolved= (Specific heat capacity)(Mass of solution)(Change in Temp) 3. The attempt at a solution -81.5=(4.18J/C x g)(mass of soln, which I cannot calculate)(Tf-25C) I worked out the mass of soln in the book problem to be 1.373. Their measurements were 11g CaCl2 and 125g H2O but the rest is the same.
