Answer:

pls mark me as BRAINLIEST

here's ur answer

Explanation:

(a) The conduction electrons per cubic meter in zinc: 

n=(65.37g/mol)/(6.02×1023mol)2(7.133g/cm3)=1.31×1023cm−3=1.31×1029m−3

(b)   EF=me0.121h2n2/3=(9.11×10−31kg)(1.60×10−19J/eV)0.121(6.63×10−34J.s)2(1.31×1029m−3)2/3=9.43eV

(c) Equating the Fermi energy to21mevF2we find 

vF=mec22EFc2
