One mole of solite AB dissolved in 20 moles of water absorbed 15.9 KJ of heat. When one male of same se is dissolved in 250 moles of water `18.58KJ`of heat is absorbed. Calculate the enthalpy of dilution

Text Solution

Verified by Experts

During dilution, heat is absorbed from `15.9KJ`to `18.58KJ`
Enthalpy of dilution =`18.58KJ-15.9KJ=2.68KJ`.
