Macmillan Learning A coulometer's sensitivity is limited by its minimum current being delivered for its minimum time. Consider a coulometer that can deliver 3.8 mA for 0.18 s. How many moles of electrons can this coulometer deliver in 0.18 s via a current of 3.8 mA? moles of electrons: mol e¯ Consider a 0.014 M solution of a two-electron reducing agent. How many milliliters of this solution would it take to deliver the same number of moles of electrons as calculated in the first part of the question? volume: mL
