Chapter 1 15 *P1.57 Consider one cubic meter of gold. Its mass from Table 1.5 is 19 300 kg. One atom of gold has mass m 0 27 25 197 3 27 10 = × F H G I K J u 1.66 10 kg 1 u kg af .. So, the number of atoms in the cube is N = × 19 300 590 10 25 28 kg 3.27 10 kg The imagined cubical volume of each atom is d 3 28 29 1 169 10 = × m m 3 3 . So d 257 10 10 . m .
