The atomic radius of a gold atom is 144×10^-12. the volume of a gold atom can be calculated using the volume of a sphere. the density of gold is 19.3 g/cm^3. how many atoms are present in a sample of gold with a mass of 1.40g using the info provided

Given:
Atomic radius of gold = 144 x 10⁻¹² m = 144 pm 
Density of gold = 19.3 g/cm³ = 19.3 x 10⁻³ kg/cm³
Mass of gold sample = 1.40 g = 1.4 x 10⁻³ kg

Calculate the volume of an atom. 
v = [(4π)/3]*(144 x 10⁻¹² m)³ = 1.2508 x 10⁻²⁹ m³

Calculate the mass of an atom.


Calculate the number of atoms in a sample of mass 1.40 g.


 5.8 x 10²¹ atoms
