Get started for freeA mixture of \(\mathrm{NaCl}\) and sucrose \(\left(\mathrm{C}_{12} \mathrm{H}_{22} \mathrm{O}_{12}\right)\) of combined mass \(10.2 \mathrm{~g}\) is dissolved in enough water to make up a 250 -mL solution. The osmotic pressure of the solution is 7.32 atm at \(23^{\circ} \mathrm{C}\). Calculate the mass percent of \(\mathrm{NaCl}\) in the mixture.
Write the equation relating osmotic pressure to the concentration of a solution. Define all the terms, and specify their units.
Determine the van't Hoff factor of \(\mathrm{Na}_{3} \mathrm{PO}_{4}\) in a \(0.40-\mathrm{m}\) solution whose freezing point is \(-2.6^{\circ} \mathrm{C}\).
What does it mean when we say that the osmotic pressure of a sample of seawater is 25 atm at a certain temperature?
Before a carbonated beverage bottle is sealed, it is pressurized with a mixture of air and carbon dioxide. (a) Explain the effervescence that occurs when the cap of the bottle is removed. (b) What causes the fog to form near the mouth of the bottle right after the cap is removed?
