Sketch a qualitative graph of the pressure versus time for water vapour above a sample of pure water and a sugar solution, as the liquids evaporate to half their original volume.
Convert a volume of 9.345 qt to liters.
Exposing a 100.0 mL sample of water at 0 掳C to an atmosphere containing a gaseous solute at 20.26 kPa (152 torr) resulted in the dissolution of\({\bf{1}}.{\bf{45}}{\rm{ }} \times {\rm{ }}{\bf{1}}{{\bf{0}}^{ - {\bf{3}}}}\))g of the solute. Use Henry鈥檚 law to determine the solubility of this gaseous solute when its pressure is 101.3 kPa (760 torr).
In a significant experiment performed many years ago, 5.6977 g of cadmium iodide in 44.69 g of water raised the boiling point 0.181 掳C. What does this suggest about the nature of a solution of\({\bf{CdI}}_2\)?
