Sure, let's carefully analyze the relationship between Avogadro's number and a mole to answer this question.
First, it's essential to understand what Avogadro's number is. Avogadro's number is a fundamental constant in chemistry that represents the number of constituent particles (usually atoms or molecules) in one mole of a substance. This number is approximately [tex]\(6.022 \times 10^{23}\)[/tex].
Now, let's look at each option:
A. Avogadro's number of items equals one mole of the items.
- By definition, one mole of any substance contains exactly Avogadro’s number of particles. This means that if you have one mole of any element or compound, you have [tex]\(6.022 \times 10^{23}\)[/tex] units (atoms, molecules, etc.) of that element or compound.
B. Avogadro's number is a larger amount than one mole.
- This option is incorrect because Avogadro's number is not larger; it is defined as the quantity in one mole.
C. Avogadro's number can be used as a conversion factor; a mole cannot.
- This is not true. Both Avogadro's number and the mole can be used as conversion factors. We often convert between the number of particles and moles using Avogadro's number.
D. A mole can be used as a conversion factor; Avogadro's number cannot.
- This is also incorrect. As previously mentioned, both can serve as conversion factors.
Given this information, the correct answer is:
A. Avogadro's number of items equals one mole of the items.
