Calculate the Enthalpy of Solution for the Dissolution of Lithium

question 116

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
