The key difference between cell and atom is that a cell is made of molecules whereas atoms make up molecules. Cells are the smallest functioning unit in a living organism. ... Meanwhile, atoms make up these macromolecules. Hence, an atom is the smallest unit of matter.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
