Formula Units:

According to avogadro's law, 1 mole of every substance contains avogadro's number of particles and weighs equal to its molecular mass.

To calculate the moles, we use the equation:

a. moles in 14.08 g of =

molecules in 14.08 g of =

b. moles in 17.75 g of NaCl =

molecules in 17.75 g of =

formula units 17.75 g of =

c. moles in 20.06 g of  =

formula units in 20.06 g of  =

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
