    Given that,

    Mass density of gold \rho=1.91\times10^{4}\ kg/m^3

    Suppose, The volume of gold is 1.23 cm³

    We need to calculate the mass of gold

    Using formula of density

    \rho=\dfrac{m}{V}

    m=\rho\times V

    Where, m = mass

    \rho =density of gold

    V = volume

    Put the value into the formula

    m=1.91\times10^{4}\times1.23\times10^{-6}

    m= 2.34\times10^{-2}\ kg

    m=23.4\ gram

    Hence, The mass of gold is 23.4 gram.
