Calculate the average density of a single Al-27 atom by assuming that it is a sphere with a radius of 0.143nm. The masses of a proton, electron, and neutron are 1.6726 x 10-24g, 9.1094 x 10-28g, and 1.6749 x 10-24g respectively. The volume of a sphere is 4Ļr3/3, where r is its radius. Express the answer in grams per cubic centimeter. The density of aluminum is found experimentally to be 2.70 g/cm3. What does that suggest about the packing of aluminum atoms in the metal?
