1. calculate the expected change in temperature for 4.5 g of NH4NO3 dissolved in 100.0 mL of H20. Assume that the calorimeter absorbs no heat. (ie. Ccal=0) 2. Calculate the change in temperature for 4.50 g of CaCl2 dissolved in 90.0 mL of H20. Assume that the calorimeter absorbs no heat (ie. Ccal=0)
