Question

There is 1.18 g of LiCl(s) dissolved in 26.0mL of water that is initially 21.0°C.

a) Write the chemical

equation for the dissolution of LiCl(s)

b) Calculate the molar enthalpy of dissolving LiCl(s) in water. Is this process endothermic or exothermic?

c) Calculate the amount of heat absorbed/released when 1.18 g of LiCl(s) dissolves.

d) Calculate the final temperature of the solution. You can assume the heat capacity of solution is equal to the heat capacity of water (density of water = 1g/mL, Cp(water= 4.184 J/g°C)
