### n and significant figures

In electrochemical problems like nernst involving n, the transfer of electrons, does that affect the final answer's signifcant figures, because that would make all the final answers 1 sig fig?

Considering that it would make all of our answers have one sig fig, we would probably use the number that has next least number of sig figs. Also, we know the exact value for n, so it has "unlimited" sig figs in a sense.

How do you determine what n is?

The value of n is determined by the electrons that are canceled out when balancing the redox reaction
