Homework Statement
An n-type silicon (Si) is produced by doping with phosphorus (P).

The electrical conductivity measurement of the doped Si shows the charge-carrier concentration to be 3.091 x 1017 cm-3 at room temperature.

Calculate the doping level of P and express your answer in units of gram of P per kilogram of Si.
