    Standard temperature and pressure means 1 mole of gas = 22.4 L, so here we are producing 0.5 moles. What we really need to know however is how many moles of electrons are needed to produce 0.5 moles ...

    Solution Summary

    The solution involves a calculation of the charge (number of electrons) needed for a half reaction in electrolysis. Additionally, the time of reaction is calculated given a value of the current used.
