Question

How many moles are present if you have 4.7 X 1023 atoms of Argon ?

Answer 1

i assume you meant 10^23. so. if you have 4.7 x 10^23 atoms of Argon, you have approximately 0.781 moles of Argon.

Step-by-step explanation:

Number of moles = Number of atoms / Avogadro's constant

Number of moles = 4.7 x 10^23 atoms / 6.022 x 10^23 atoms/mole

Number of moles ≈ 0.781 moles
