In a later chapter, we shall be especially interested in "doped" semiconductors, in which small levels of impurities are added to an essentially pure semiconductor in order to produce desirable
electrical properties. For silicon with 6 x 1021 aluminum atoms per cubic meter in solid solution, calculate the atomic percent of aluminum atoms.
Express your answer to three significant figures.
