This is the info I am given...
e = 1.6 ´ 10–19 C
NA = 6.0 ´ 1023 particles / mole
Molar mass of zinc = 65.4 grams
In a chemical cell, the energy released by chemical attack on a metal, say zinc, as in many chemical reactions, is about 300 kJ per mole of metal attacked.
What is the potential energy given to each coulomb of charge (i.e. the potential difference)?
Remember that each zinc atom loses 2 electrons to become a Zn2+ ion.
