Calculate the average density of a single A1-27 atom by assuming that it is a sphere with a radius of 0.143 nmThe masses of a proton, electron, and neutron are 1.6726 x 10^-24 g, 9.1094 x 10^-28 g, and 1.6749 x 10^-24 g, where r is its radiusExpress the answer in grams per cubic centimeterThe density of aluminum is found experimentally to be 2.70 g/cm^3What does that suggest about the packing of aluminum atoms in the metal?
