Charge on the electrons in a nickel coin
We want to find how many Coulombs of charge are on the electrons in a nickel coin. Follow this method.
a) A nickel coin has a mass of about 5.172 g. Each mole (6.02 * 10^23 atoms) has a mass of about 57.98 g. Find the number of atoms in nickel coin.
b) Find the number of electrons in the coin. Each nickel atom has 28 electrons/atom.
c) Find the magnitude of the charge on the electrons. Answer in units of Coulombs.
a) Mass of Nickel coin = 5.172 g
6.02 * 10^23 atoms of Nickel have a mass of 57.98 g.
So the number of atoms of Nickel in 5.172 g Nickel coin = ...
