How many faradays of electricity are involved when 5.0 l of o2 at stp is converted to h20 in acid solution?

0.893 Faraday

Explanation:

Hello,

In this case, the undergoing chemical reaction is given as follows:

Now, the oxygen's half-reaction turn out into:

Let us identify that four electrons were involved since there are two oxygens that transfer two electrons for a total of four. In such a way, to compute the faradays of electricity, one multiplies the changing moles by the amount of transferred electrons as shown below:
