Passage / Comprehension
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 II: 1 mole of CaCl2 dissolved in 17 moles of water.
Options:
Answer:
B
Solution:
n = 17: ΔH = -60(17)/(17 + 3) = -1020/20 = -51.0 kJ. Ans (b).
