Hank, a neurotic fitness buff, decided to "flush the toxins from his body" by drinking 10 liters of distilled water in 60 minutes. Hank weighed 198 pounds and appeared to be a normally hydrated, healthy young man before he started. Assume that he experienced some brain swelling as a result of rapidly drinking water. If you only had access to a hypertonic sodium chloride solution, how much 5% sodium chloride should you administer IV to return Hank's osmolarity to 300 mOsm/L.
