Mercedes · Answer 1

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

Answer:

1.42 x 10^24 xenon atoms
