How many moles of argon, Ar, are in 1.63×1024 Ar atoms?

Explanation:

Hello! To begin, remember Avogadro's number, 6.02*10^23 molecules!

You take your number of Ar atoms and divide it by Avogadro's number:

= 2.7076412 moles...

round to 3 sig dig's (based on "1.63")

Final answer = 2.71 moles Ar

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
