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"#
