28.29.Solve:The density of aluminum is 2700 kg/m3, so 1.0 m3of aluminum has a mass of 2700 kg. Theconduction-electron density is the number of electrons in 1.0 m3. Because the atomic mass of aluminum is 27 u, 27 gof aluminum contains NA=6.02 ×1023atoms. Thus, the number of aluminum atoms in 2700 kg of aluminum is602 102760 102328..×()=×g2700 kg
