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.
