Question

the chemical formula for a molecule of acetaminophen is displayed below. use the chemical formula to answer the following question. \\(\ce{c8h9no2}\\) which of the following statements accurately describes the chemical formula for a molecule of acetaminophen? there are three different elements that make up the chemical formula for a molecule of acetaminophen. there are 19 total atoms involved in the chemical formula for a molecule of acetaminophen. there are 20 total atoms involved in the chemical formula for a molecule of acetaminophen. there are a total of 2 atoms of nobelium in one molecule of acetaminophen

Explanation:

To solve this, we analyze the chemical formula of acetaminophen, \( \ce{C_8H_9NO_2} \):

Step 1: Identify elements

The formula has \( \ce{C} \) (Carbon), \( \ce{H} \) (Hydrogen), \( \ce{N} \) (Nitrogen), and \( \ce{O} \) (Oxygen) – 4 elements. So the first statement is wrong.

Step 2: Calculate total atoms

Sum the subscripts: \( 8 (\ce{C}) + 9 (\ce{H}) + 1 (\ce{N}) + 2 (\ce{O}) = 20 \) atoms.

Step 3: Check Nobelium

Nobelium (\( \ce{No} \)) is not in \( \ce{C_8H_9NO_2} \), so the last statement is wrong.

The correct statement is: "There are 20 total atoms involved in the chemical formula for a molecule of acetaminophen."

Answer:

There are 20 total atoms involved in the chemical formula for a molecule of acetaminophen.
