Question

How many oxygen atoms in an 8 mole quantity of carbon dioxide?

Answer 1

There are `24*mol` of atoms in `8*mol` of `CO_2`....

Explanation:

Before we do this in detail, let us suppose that the question asked....`"find the number of atoms in 8 DOZEN molecules of"` `CO_2`.

And thus, there are `3*"atoms"` `*"molecule"^-1` `xx8xx12` `"molecules"`

`=3xx8xx12=288*"atoms"`

The question asked here is ENTIRELY ANALOGOUS EXCEPT that instead of `"dozens"` we use `"moles"` where `1*"mole of stuff"` `-=` `6.022xx10^23*"individual items of stuff"`.

And thus there are `8xx6.022xx10^23*"atoms"`

`~=48xx10^23*"atoms"`
