space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

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

c. electrical charges of ionic bonds.
