Answer:
1.7*10^{12}Ucm^-1
Explanation:
The answer to this question is obtained by using the following formula:
[tex]\sigma=nq\mu_e[/tex]
sigma: conductivity
q: charge of the electron = 1.61019*10^{-19}C
mu_e: electron mobility = 8104 m^2/Vs
n: free electron concentration = 1.31029/m^3
By replacing you get:
[tex]\sigma=(1.31*10^{29}/m^3)(1.61*10^{-19}C)(8104 m2/Vs)=1.709*10^{14}\Omega^{-1}m^{-1} \\\\1.709*10^{14}\Omega^{-1} (1*10^{2}cm})^{-1}=1.7*10^{12}\Omega^{-1}cm^{-1}[/tex]
the result obained is not 5.9mU.cm. This is because temperature effects has not taken into account.
