Make the simplifying assumption that the atoms are arranged in a "cubic" array, so that an atom of diameter d occupies an amount of space d3 in the solid. Note that the density is equal to the mass of one atom divided by d3. Of course, you need to convert to SI units. 1 g = 1e-3 kg. 1 cm3 = (0.01 m)3 = 1e-6 m3. 3. (This is Problem 3.2, page 82.)

2. The number of particles e.g. atoms, ions, molecules, electrons, cows, cars are all measured in terms of moles. 3. The number of particles in one mole is called the Avogadros Constant. It is denoted “L”. The Avogadros Constant contain 6.023 x10 23 particles. i.e. 1mole = 6.023 x10 23 particles = 6.023 x10 23
