//Using Avogadro no. find the numerical value of concentration of atom in Germanium

//Given Values

Av=6.02*(10^23) //Avogadro No.
m=72.6 //Molar mass of germanium in gm/moles
d=5.32//density in gm/cm^3

conc = (Av/m)*d //Concentration of atom in germanium

disp('atom/cm^3',conc,'The concentration of germanium atom is=');
