Answer:

How many moles of #CO# do you have.........?

Explanation:

And we know that by definition, #1*mol# of stuff contains #6.022xx10^23# individual items of that stuff, i.e. #N_A# individual items, where #N_A-=6.022xx10^23*mol^-1#.

.......And here your stuff is #CO#, where a mole of said stuff has a mass of #28*g#....

How many atoms in this molar quantity?

Note that this question is effectively asking #"how many atoms are there in dozen carbon monoxide molecules?"#

I make it #"3 dozen.."#

If you can answer this question, you can certainly answer the former.
