100%
An aqueous solution of sodium iodide (NaI) has a molality of 0.150 mol·kg–1 at 18°C.
a) Convert this concentration to molarity. You may assume that the solution has a
density of 1.00 g·cm–3
at 18°C. Report your answer to 3 significant figures.
Mm(NaI) = 149.9 g/mol
Mm(H2O) = 18.0 g/mol
b) Assuming a boiling point elevation constant of 0.51 °C/m and a Van’t Hoff factor
equal to 1.76, calculate the boiling point of the solution.
c) To make homemade ice cream, you cool the milk and cream by immersing the
container in ice and a concentrated solution of rock salt (NaCl) in water. If you want
to have a water-salt solution that freezes at –10°C, what mass of NaCl must you add
to 3.0 kg of water? You may assume the Van’t Hoff factor for NaCl is equal to 1.85.
Mm(NaCl) = 58.4 g/mol
