The process of distillation is used to remove impurities like chlorine and fluorine from water. the water is heated
until it becomes steam and then cooled and collected as a liquid. what property is used to separate the water from the
elements chlorine and fluorine?

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
