The analgesic drug has a metabolic decomposition that follows 1st order kinetics, with a half-life of 150 minutes. The drug is administered to a patient and the initial concentration of the drug is 0.00460 mol L-1. Calculate the concentration (in mol L-1) of the drug after 600 minutes. Give your answer to three significant figures using E notation (e.g. 3.25 x 105 could be entered as 3.25e-5, 3.25e-05, 3.25E-5 or 3.25E-05) and without units. Answer:
