An Aqueous Solution Is 1

Short Answer

An aqueous solution is 1.00% NaCl by mass. Its density is 1.071 g/mL at 25°C. The observed osmotic pressure of this solution is 7.83 atm at 25°C.
A. What fraction of the moles of NaCl in this solution are ion pairs?
B. Calculate the freezing point that would be observed for this solution; K_f for H₂O = 1.86°C kg/mol.
