pH using Nernst Equation

W2010 Q4B

1.) How do you know "the cell emf was +0.060V." means Ecell and not E*cell?

2.) How do you know n=1? I thought n=2 from Q4A, which was the redox reaction where 2 electrons were transferred.

We would know it's not E*cell because that would be the standard cell emf, i'm not sure about the n though, could someone help? I'm wondering about that too...

I think 4B is separate from 4A, which is why you don't use n=2. They aren't the same question, and use different chemicals. As for how they found n=1, I'm not sure!
