Note the average atomic mass of copper on the nano-balance. Add atoms to the
larger balance until it registers the same number in g) as the reading on the nano-balance
(in u). Use the Exponent slider to help get the correct amount. Stop adding atoms when the
readings on both balances matchi exactly to the nearest 0.001 y).
How many atoms did you need to add?
