How many moles are in 12.044 x 10^64 atoms of Ar?

#moles Ar = 2 x 10⁴¹ moles

Explanation:

A mole is the mass of substance that contains 6.023 x 10²³ particles of specified substance. So, one might think 'how many 6.023 x 10²³rds are in 12.044 x 10⁶⁴ atoms. That is ...

moles Ar = 12.044 x 10⁶⁴atoms / 6.023 x 10²³ atoms/mole = 2 x 10⁴¹ moles of Argon.

the answer for sodium is 0.186

the answer for rubidium is 0.251

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
