  1. How far apart are they? Do they touch. If so,
    Make a proportion.

    (3.14E-8cm/1 atom) = (2.54cm/x atoms).
    Solve for x.

  3. 1 Inch = 2.54 cm
    1 Na atom has a diameter of 3.4 x 10^-8 cm
    X Na atoms = 2.54 cm
    (3.4 x 10^-8)x = 2.54

    Find X= ?
    X= 8.09 x 10^7 Na atoms.
