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.
if the diameter of a sodium atom is 3.14×10−8 cm, how many sodium atoms would fit along a line exactly 1.00 inch long?

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.
