Answer:

Well a molar quantity specifies #6.022xx10^23# individual items of stuff..........

Explanation:

And so we take the quotient...........

#(4.21xx10^22*"molecules")/(6.022xx10^23*"molecules"*mol^-1)#

#=0.0700*mol#, and thus there #0.0700# moles of #SO_3#, #0.0700# moles of #"S atoms"#, and #0.210# moles of #"oxygen atoms"#.
