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

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?
