Examples ( Dr. Bülent BELİBAĞLI )

Example: What are the partial pressures of H 2 and He gases in the gaseous mixture described in the previous example ?
Solution:

Total pressure of wet gas is equal to atmospheric pressure (P bar ) if the water level is the same inside and outside.

Example: In the following reaction 81.2 mL of O 2 (g) is collected over water at 23⁰C and barometric pressure 751 mmHg. What must have been the mass of Ag 2 O(s) decomposed ? (Vapor pressure of H 2 O at 23⁰C = 21.1  mmHg).
