A teacher has given a lab student a white chemical sample and asks her to confirm that it contains 7.03 × 1023 formula units of sodium hydroxide (NaOH). Using the balance in the laboratory, what mass of NaOH would the student have to find to verify that her teacher was correct? Round your answer to 3 significant figures.
