Certainly! Here's a precise problem for the student to solve:Calculate the standard enthalpy change ($\Delta H^\circ$) for the dissolution reaction of 5.00 g of lithium chloride ($\text{LiCl}$) in 150.0 mL of water, given that the density of water is 1.00 g/mL and the final temperature of the solution is 25.0$^\circ$C. The molar enthalpy of solution of $\text{LiCl}$ is -3.00 kJ/mol.
