Question:

In the course of the electrolysis of water, hydrogen gas was collected at one electrode over water at 20.°C when the external pressure was 756.7 Torr. The vapor pressure of water at 20.°C is 17.54 Torr. The volume of the gas was measured to be 0.220 L.

(a) What is the partial pressure of hydrogen?

(b) The other product of the electrolysis of water is oxygen gas. Write a balanced equation for the electrolysis of water into H2 and O2.

(c) What mass of oxygen was also produced in the reaction?
