How many xenon atoms are contained in 2.36 moles of xenon? 3.92 x 1024 xenon atoms 2.55 x 1023 xenon atoms 1.42 x 1024 xenon atoms 7.91 x 1025 xenon atoms 1.87 x 1026 xenon atoms?

The number of atoms can be calculated by multiplying the number of moles with the Avogadros number. The Avogadros number is 6.022 x 10^23 atoms / moles, therefore:

number of atoms = 2.36 moles * 6.022 x 10^23 atoms / mole

number of atoms = 1.42 x 10^24 atoms

1.42 x 10^24 xenon atoms
