#"An unfeasibly large number of moles........"#

Explanation:

A mole of #NO_2# contains #6.022xx10^23# individual molecules........and has a mass of #44*g#.

But #5.40xx10^224# nitric oxide molecules represents a molar quantity of:

#(5.40xx10^224*"molecules")/(6.022xx10^23*"molecules"*mol^-1)#

#=8.97xx10^200*"moles"#

This molar quantity has a mass MANY times the mass of the galaxy, and probably the universe, so your question is unreasonable.

Do you mean #5.40xx10^24# molecules?
