The diameter of a US penny is 19 mm. The diameter of a sliver atom is only 2.88 Å

Question: How many silver atoms could be arranged side by side in a straight line across the diameter of a penny?

Solution:

Number of Ag atomes = Diameter of a penny / Diameter of a Ag atom = (19 × 10

Number of Ag atomes = 6.5 × 10
