Answer:

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:

[tex]\frac{1.63 * 10^{24} Ar atoms}{6.02 * 10x^{23} }[/tex] = 2.7076412 moles...

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

Final answer = 2.71 moles Ar
