Answer 1

The correct answer is 3.6 × 1024.Key Points

CH₃OH is the chemical formula for methanol, which is a colorless liquid with a mild odor.
One mole of any substance contains 6.02 x 10²³ particles, which is known as Avogadro's number.
In CH₃OH, there are 6 atoms in one molecule: 1 carbon, 4 hydrogen, and 1 oxygen.
To calculate the number of atoms in one mole of CH₃OH, we multiply Avogadro's number by the number of atoms in one molecule, which is 6.
Hence, the correct answer is 6.02 x 10²³ x 6 = 3.6 x 10²⁴ atoms in one mole of CH₃OH.

Additional Information

Usually, the Avogadro constant is represented by NA or L.
The quantity of substance in a sample, which is calculated by dividing the number of constituent particles by NA, uses it as a normalizing factor.
Depending on the substance and the type of reaction, the units could be molecules, atoms, ions, or electrons.
