The integral enthalpy of solution of one mole of CaCl2 in n mole of water is given by the equation ΔH = -60n/(n+3) kJ/mol. Determine ΔH for the following solutions:

Solution I: 1 mole of CaCl2 dissolved in 6 moles of water.

Options:

Answer:
C
Solution:

n = 6: ΔH = -60(6)/(6 + 3) = -360/9 = -40.0 kJ. Ans (c).
