The atomic mass of germanium is 72.6 and its density is 5.47g $c m^{- 3}$ . What is the atomic volume of germanium?

Open in App

Solution

$A t o m i c v o l u m e = \frac{G r a m a t o m i c m a s s}{D e n s i t y}$
$= \frac{72.6 g}{5.47 g c m^{- 3}} = 13.27 c m^{3}$

Q. A strong current of trivalent gaseous boron passed through a germanium crystal decreases the density of the crystal due to part replacement of germanium by boron and due to interstitial vacancies created by missing Ge atoms. In one such experiment, one gram of germanium is taken and the boron atoms are found to be

150

ppm by weight when the density of the Ge crystal decreases by

4 %

. Calculate the percentage of missing vacancies due to germanium which are filled up by boron atoms. Atomic weight of Ge
