A sample of n-type silicon

A sample of pure silicon is doped with a trivalent impurity whose each atom creates a hole the concentration holes in pure silicon is 7xx10^(15) holes per cubic metre and density of silicon is 5xx10^(23) a pure silicon sample by a factor of 120 calculate approximately the proportion in which the impurity is added

An-type and P-type silicon can be obtained by doping pure silicon with
