If the dissolution of CaCl2•2H2O (147.02 g/mol) is expected to release 44.8 kJ of energy per mole of CaCl2•2H2O dissolved, then what is the expected change in temperature (in oC) if 2.74 grams of CaCl2•2H2O are dissolved in 10.00 mL of water (density of 1.00 g/mL and specific heat capacity of 4.184 J/g•oC)? (Give answer as the absolute value of the temperature change; do NOT include negative sign if temperature decreases.)
