Question

Chemical analysis of a silicon crystal reveals gallium at a level of 3.091×10−8 atomic percent. Assuming that the concentration of thermally excited charge carriers from the Si matrix is negligible, what is the density of free charge carriers (free carriers/cm3) in this Si crystal?

Answer 1

(6.023*10^23)/(12.05)=m
m*(3.091*10^-8)*(10^-2)=

Answer 2

This is a question from the second midterm of 3.091x by edx. Stop cheating, it's silly and pointless.
