Question
The van't Hoff factor for a 0.047 m aqueous solution of magnesium sulfate is 1.3. What is the freezing point of the solution if Kf = 1.86degreeC/m? Crude oil pumped out of the ground may be accompanied by formation water, a solution that contains high concentrations of NaCl and other salts. If the boiling point of a sample of formation water is 2.0degreeC above the boiling point of pure water, what is the molality of particles in the sample? Calculate the osmotic pressure at 25degreeC across a semipermeable membrane separating seawater (1.14 M total particles) from a 0.44 M solution of aqueous NaCl. Use the information given below to calculate the lattice of calcium chloride.Explanation / Answer
Osmatic pressure= CRT
C=(1.14+.44)/2=.79
pressure is 19.33atm
