To begin with, we need to convert from amps to coulombs: 60 minutes * 60s/min * 15 C/s = 54000 coulombs. Next, we can use this value of charge to convert to moles of electrons: 54000 coulombs * 1 mol e-/96485C = 0.559 mol e-. Then, we can use stoichiometry to convert from mol e- to moles of chromium.AP® Chemistry 2007 Free-Response Questions Form B The College Board: Connecting Students to College Success.
