Answer:
the density of the electrum is 14.30 g/cm³
Explanation:
Given that:
The equilibrium fraction of lattice sites that are vacant in electrum =
Number of vacant atoms =
the atomic mass of the electrum = 146.08 g/mol
Avogadro's number =
The Number of vacant atoms = Fraction of lattice sites × Total number of sites(N)
=
× Total number of sites(N)
Total number of sites (N) =
Total number of sites (N) =
From the expression of the total number of sites; we can determine the density of the electrum;
where ;
= Avogadro's Number
density of the electrum
= Atomic mass
Thus; the density of the electrum is 14.30 g/cm³
