How many moles of copper are in 6,000,000 atoms of copper?

Question

anonymous · Answer

just take 6000000 and multiply it byt the atomic mass

anonymous · Answer

1 copper has 63.54 mol/g

Wrong @Maisa101  
you are using dimensional analysis to cancel out the number of atoms given by avogradro's number: $6.022 \times 10^{23} \large \frac{mole}{atom}$ That means you are DIVIDING, not multiplying.

anonymous · Answer

hmmm, i'm sorry i'm a little confused what's dimensional analysis?

abb0t · Answer

Same as what you did with fractions in algebra, except the process is called "dimensional analysis" in chemistry. Crossing out like terms to get the desired product.

ahh, I see then. Thanks for correcting me, I would hate to give someone the wrong answer.

1 mole of copper atoms contains Avogadro's number ($N_A =6.02214179*10^{23}$) atoms.  Clearly, 6,000,000 atoms is only going to give us a small fraction of a mole!

It might not be as clear to them as it is for you. , otherwise they wouldn't be here seeking help :)

Thank you all for the help :)
I did get it eventually :D
