Answer:
5 moles of O2are required, you can see it in your equation.
To solve this problem we will apply Ohm's law. The law establishes that the potential difference V that we apply between the ends of a given conductor is proportional to the intensity of the current I flowing through the said conductor. Ohm completed the law by introducing the notion of electrical resistance R. Mathematically it can be described as

Our values are


Replacing,



Therefore the smallest resistance you can measure is
