Given that,
Mass density of gold [tex]\rho=1.91\times10^{4}\ kg/m^3[/tex]
Suppose, The volume of gold is 1.23 cm³
We need to calculate the mass of gold
Using formula of density
[tex]\rho=\dfrac{m}{V}[/tex]
[tex]m=\rho\times V[/tex]
Where, m = mass
[tex]\rho[/tex] =density of gold
V = volume
Put the value into the formula
[tex]m=1.91\times10^{4}\times1.23\times10^{-6}[/tex]
[tex]m= 2.34\times10^{-2}\ kg[/tex]
[tex]m=23.4\ gram[/tex]
Hence, The mass of gold is 23.4 gram.
