Question

Consider a tank containing a toxic chemical that is leaking slowly into the atmosphere, emitting 1 kg per hour for 12 hours before the leak is discovered and plugged. The chemical reacts quickly once it gets into the atmosphere with a half life of 4.159 hours. For how many hours is the total mass in the atmosphere greater than 4 kg? Consider both the time prior to the discovery of the leak, and the time after the emission is stopped to come up with the total number of hours.

Expert Solution
