Final answer:
In chemistry, one mole of any substance, including xenon, contains Avogadro's number of atoms, which is 6.022 x 10^23.
Step-by-step explanation:
Number of Atoms in One Mole of Xenon
To determine the number of atoms in a mole of Xenon, we refer to Avogadro's number which is a fundamental constant in chemistry. This number is precisely defined as 6.02214076 × 1023, but often the value is approximately used as 6.022 × 1023.
Therefore, in one mole of any substance, including Xenon, there are 6.022 × 1023 atoms.
This universal constant represents the number of particles, such as atoms, ions, or molecules, that are contained in one mole of a substance. We can say that a mole is a bridge between the atomic scale and the macroscopic scale, allowing chemists to count and use substances in the laboratory and industry with practical amounts.
Given the options provided in the student's question, the correct answer to the question of how many atoms are in one mole of xenon is:
A) 6.022 x 1023
