Select the correct answer.

How many particles are in one mole?

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]



Answer :

To determine the correct number of particles in one mole, we rely on Avogadro's constant. Avogadro's constant tells us how many particles (atoms, molecules, etc.) are in one mole of a substance.

Avogadro's constant is approximately [tex]\(6.022 \times 10^{23}\)[/tex] particles per mole. This means that in one mole of any substance, there are about [tex]\(6.022 \times 10^{23}\)[/tex] particles.

Now, let's look at the options provided:

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]

Clearly, the value [tex]\(6.022 \times 10^{23}\)[/tex] exactly matches Avogadro's constant. As a result, the correct answer is:

A. [tex]\(6.022 \times 10^{23}\)[/tex]
