Fullerenes and moles question

[From: ] [author: ] [Date: 12-04-25] [Hit: ]
Any help would be appreciated, thank you.-Ok,We know that 1 mol of any compound has 6.So I set it up like this,720 g of fullerenes have 6.......
A fullerene molecule consists of 60 carbon
atoms.
Approximately how many such molecules are
present in 12 g of this type of carbon?
The answer is 1.00*10^22, but I don't understand why.
Any help would be appreciated, thank you.

Ok, So its molecular weight is 60 x 12 = 720g/mol

We know that 1 mol of any compound has 6.023 x 10^23 molecules (Avogadros number)

So I set it up like this,

720 g of fullerenes have 6.023 x 10^23 molecules
12g " " " " (12g x 6.023 x 10^23 molecules)/720g
= 1.0038 x 10^22 molecules


Hope this helps
