Problem- A digital watch battery draws 0.25 mill amperes of current, which is provided by a mercury battery whose net reaction is:

HgO(s) + Zn(s) ? ZnO(s) + Hg(l)

If a partially used battery contains 0.80 g of each of these four substances, for how many hours will the watch continue to run?

Provide me complete explanations of above question so I can get high score
