Final answer:
Danielle Young Bear should speak to a pharmacist for guidance on acetaminophen dosage to avoid liver damage and safely manage pain. Children require specific formulas of acetaminophen, and care is needed when considering combination pain relievers. The molecular mass of acetaminophen and Avogadro's number are needed to calculate the number of molecules in a dose.
Step-by-step explanation:
The best advice to give Danielle Young Bear regarding over-the-counter (OTC) medications and daily doses of acetaminophen would be: C) talk to the pharmacist if buying a medication containing acetaminophen. This is because pharmacists are trained to provide important information about medication dosage and potential interactions with other substances, such as alcohol. It is important not to exceed the recommended dose of acetaminophen, as too much can lead to severe liver damage. When considering giving acetaminophen to children, make sure to select the appropriate formula for infants or older children and always follow the label directions. Always be aware that acetaminophen is present in many combination pain relievers along with other drugs, and be cautious of your total intake.
To answer the question regarding the number of molecules in a 325 mg Tylenol pill, you would need to calculate the molecular mass of acetaminophen (C8H9NO2) and then use Avogadro's number to determine the number of molecules in 325 mg of the substance.
