To calculate the heat of hydration use the formula
\(\displaystyle\triangle{H}_{{{s}{o}{l}}}=\triangle{H}_{{{l}{a}{\mathtt{{i}}}{c}{e}}}+\triangle{H}_{{{s}{o}{l}{v}}}\)
where deltaH solvation is the heat of hydration of 1mol Li+and Cl- ions substitute the respective values to get the answer.
DeltaH solv = -865.1KJ/mol
