The equilibrium fraction of lattice sites that are vacant in silver (Ag) at 700°C is 2 × 10-6. Calculate the number of vacancies
True [87]

Answer:

1.16*10^{23} vacancies/m^3

Explanation:

Data given

temperature =700c

Density=10.35g/cm^3

but

\frac{N_v}{N}=2*10^{-6}\\N_v=2*10^{-6}N\\

Nv is the number of vacant site and N is the number of lattice site.

Since the number of lattice site can also b computed as

N=\frac{p_{Ag} * N_A}{A_{AG}} \\N=\frac{6.022*10^{23} * 10.35*10^6g/m}{107.87g/mol} \\N=5.78*10^{28}atom/m^3

if we substitute the value of the number of lattice into the first equation, we arrive at

N_v=2*10^{-6} *5.78*10^28\\N_v=1.16*10^{23} vacancies/m^3
