How to find the mol contained in a sample of 5.84 x 10^23 atoms of a specific element?
I have a question "How many mol are contained in a sample of 5.84 x #10^32# atoms of tin (Sn)?" that I don't know how to answer. I would really like an explanation and how to, So I can work out any further questions relating to this. Thank you.

Explanation:
You know that
And so we take the following quotient to get the molar quantity:
Why do I include the units? Because then I get an answer with the appropriate dimensions, if I have followed the right order of operation in my calculation...here I get an answer in moles as required....
And what is the mass of this quantity?
I think there is a typo in your original question...
Explanation:
To convert from atoms to moles of an element/molecule, you must divide by Avogadro's number (
Anytime you are converting from one unit to another, you must cancel out your initial units so that the remaining units are whatever units the question is asking for. So let's consider that the question initially gave you moles of a tin sample and asked you to determine how many atoms were in that sample, you then have to multiply by Avogadro's number to get the unit of atoms.
Explanation:
1 mole of anything is
