What is the molality, Molarity, mass percent and mole fraction of NaCl in this solution. Assume that the density of the resulting solution is 1.03 g/ml Q6. Indicate the type of solute-solvent interactions operating in each of the following solutions. Rank them in the order from weakest to strongest interactions a) Iodine(I2) in CHCl3 b) Ammonia (NH3) in water c) MgCl2 in water d) HCl in Acetonitrile (CH3CN) Q7. A solution was prepared by dissolving 0.400 g of a polypeptide (a non-electrolyte) in water to form 1.00 L solution. The solution has an osmotic pressure of 3.74 torr at 27 ºC. What is the molar mass of the polypeptide? Q13. A 0.100 M solution of an aqueous ionic compound has as osmotic pressure of 8.3 atm at 25 °C. Calculate the van't Hoff factor for the ionic compound.
