Multiple Choice
Calculate the enthalpy of solution for the dissolution of lithium iodide, LiI, molar mass = 133.85 g mol-1. When 1.49 g of LiI is dissolved in a coffee cup calorimeter containing 75.0 mL of water the temperature increased from 23.5 °C to 25.7 °C. The specific heat of water is 4.184 J g-1 °C-1, and assume the density of the solution is 1.00 g mL-1.
A) 30 kJ mol-1
B) 18 kJ mol-1
C) -62 kJ mol-1
D) -39 kJ mol-1
E) -76 kJ mol-1
