Derive an expression for the final temperature T. of the mixture ofThe maximum dose over 24 hours for OTC (over the counter use) of acetaminophen (medication in Tyleonol) is 4,000 mg. Many OTC and prescription medications contain acetaminophen along with other ingredients. Acetaminophen can be found in many cold medicines and in prescription painkillers such as Norco, which also contains the addictive opiod hydrocodone. Keeping track of sources and amount of acetaminophen is very important for your health. Abuse of Norco due to the opiod can also lead to toxic/lethal doses of acetaminophen. There are now strict regulations on the number of tablets of Norco that can be prescribed (7 day maximum per prescription, not refillable without another prescription). A tablet of Norco contains 325 mg of acetaminophen. Thirty tablets are in a week-long prescription post major-surgery to aid in recovery.
