The large diversity of biological molecules depends on atoms of the element this element can make stable bonds to itself and to atoms of other elements. without this element, the large macromolecules that make up most of the molecules in living organisms would not be possible.

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa

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
