Electrical and thermal conductivity of Ag
The electron drift mobility in silver has been measured to be 56 cm2 V-1 s-1 at 27 °C. The atomic mass
and density of Ag are given as 107.87 amu or g mol“1 and 10.50 g cm-3, respectively.
a. Assuming that each Ag atom contributes one conduction electron, calculate the resistivity of Ag at 27
°C. Compare this value with the measured value of 1.6 × 10-8 Ω m at the same temperature and
suggest reasons for the difference.
