To determine how many particles are in one mole, we refer to a fundamental constant in chemistry known as Avogadro's number. Avogadro's number gives us the number of constituent particles (usually atoms or molecules) contained in one mole of a substance. This number is crucial in chemical calculations and helps relate macroscopic quantities of substances to the number of particles in those quantities.
Here are the given options:
A. [tex]\(6.022 \times 10^{23}\)[/tex]
B. [tex]\(2.066 \times 10^{23}\)[/tex]
C. [tex]\(6.023 \times 10^{22}\)[/tex]
D. [tex]\(3.026 \times 10^{22}\)[/tex]
By evaluating the given options, we can see that the correct value is closest to Avogadro's number, which is approximately [tex]\(6.022 \times 10^{23}\)[/tex].
Therefore, the correct answer to the question "How many particles are in one mole?" is:
A. [tex]\(6.022 \times 10^{23}\)[/tex]
This value represents the number of atoms or molecules in one mole of any substance, and it is universally accepted in scientific calculations.
