Answer» What mass of phosphorous is needed to dope $1.0 g$ of silicon so that the number density of conduction electrons in the silicon increased by a multiply factor of $10^{6}$ from the $10^{16} m^{- 3}$ in pure silicon. (Take the concentration of silicon atoms $n_{Si} = 5 \times 10^{28} m^{- 3} Molar mass of silicon M_{Si} = 28.1 g Molar mass of phosphorous M_{P} = 30.97 g Avogadro number N_{A} = 6.023 \times 10^{23})$
