How long does it take to produce 0.02l of oxygen during electrolysis of water?

The time required to produce 0.02 liters of oxygen during the electrolysis of water depends on several factors, including the current applied, the efficiency of the electrolytic cell, and the temperature. Generally, using a typical current of around 1 ampere and assuming ideal conditions, it may take several minutes to produce this volume of oxygen. For more precise calculations, specific parameters of the electrolysis setup would need to be considered.
