Hello, will someone explain how to figure out n? In the solutions manual it says that n is 6. The reaction is: 6Fe3+ + 2Cr3+ +7h2O---> 6 Fe2+ + Cr2O7 2- + 14H+

When you balance the half reactions and multiply the equations with a constant to get the same moles of electrons exchanged, it should be 6.
