Find the number of free electrons per cubic centimeter in germanium at room temperature given that there are 5.6x10-10 free electrons per atom. the density and molar mass of silicon are 5.32 g/cm3 and 72.59 g/mol, respectively.

Explanation:

given,

free electron per atom = 5.6 x 10⁻¹⁰

density of silicon = 5.32 g/cm³

molar mass of silicon =  72.59 g/mol

number of moles per cubic centimeter

           =

number of atom per cubic centimeter

           =

number of free electron per cubic centimeter

           =

           =

im not to sure what it is

found in the nucleus

has mass of one amu
