One mole of gallium (6 × 1023 atoms) has a mass of 70
grams, as shown in the periodic table on the inside front cover of
the textbook. The density of gallium is 5.9 grams/cm3.
What is the approximate diameter of a gallium atom (length of a
bond) in a solid block of the material? Make the simplifying
assumption that the atoms are arranged in a "cubic" array, as shown
in the figure. Remember to convert to SI units.

Problem 4.32 Your answer is partielly correct. Try again. One mole of magnesium (6 x 1023 atoms) has a mass of 24 grams, and its density is 1.74 grams per cubic centimeter, so the center-to-center distance between atoms is 2.84 x 10-10 m. You have a long thin bar of magnesium, 2.9 m long, with a square cross section, 0.07 cm on a side. You hang the rod vertically and attach a 64 kg mass to the bottom, and yooberve...

Unit Cells: The Simplest Repeating Unit in a Crystal
The structure of solids can be described as if they were
three-dimensional analogs of a piece of wallpaper. Wallpaper has a
regular repeating design that extends from one edge to the other.
Crystals have a similar repeating design, but in this case the
design extends in three dimensions from one edge of the solid to
the other. We can unambiguously describe a piece of wallpaper by...
