A 0.100-L solution is made by dissolving 0.441 g of
CaCl2(s) in water. (a) Calculate the
osmotic pressure of this solution at 27 °C, assuming that it is
completely dissociated into its component ions.
(b) The measured osmotic pressure of this solution
is 2.56 atm at 27 °C. Explain why it is less than the value
calculated in (a), and calculate the van’t Hoff factor, i,
for the solute in this solution. (c) The enthalpy
of solution for CaCl2 is...
