A drug is given as a single 200 mg dose orally. The oral bioavailability is 90 %. The total amount of drug recovered unchanged in the urine is 110 mg. Assuming that the drug follows first-order elimination kinetics and the drug has a volume of distribution ($V_d$) of 80 liters and an elimination half-life of 8 hours, calculate the hepatic clearance for this patient. (Provide answer in units, L/hr, and round to 1 decimal place)
