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 2011 SCORING GUIDELINES . Question 1 . 1. Each of three beakers contains 25.0 mL of a 0.100 M solution of HCl, NH 3, or NH 4 Cl, as shown above. Each solution is at 25°C. (a) Determine the pH of the solution in beaker 1. Justify your answer. pH = -log[H +] = -log(0.100) = 1.000. 1 point is earned for the correct pH.
