The vapour pressure of water at is 355 mm of Hg. 1 L vessel contains at , which is saturated with water and the total pressure being 760 mm of Hg. The contents of the vessel were pumped into 0.3 L vessel at the same temperature. What is the partial presure of ?

  1. 1350 Hg
  2. 2178.3 Hg
  3. 121.5 Hg
  4. 355 Hg
Solution: Answer: aSolution: (a) Volume of =1 L
and =760-355=405 mm Hg
Since, the temperature is constant, using Boyle's law we get
:.P'o_(2) =1350 mmHg
