Answer:

There are #1.73 × 10^24 color(white)(l)"N"_2"O"_5color(white)(l) "molecules"#.

Explanation:

1 mol of a compound like #"N"_2"O"_5# contains #6.022 × 10^23# molecules.

∴ There are

#2.88 color(red)(cancel(color(black)("mol N"_2"O"_5))) × (6.022 × 10^23color(white)(l) "N"_2"O"_5color(white)(l) "molecules")/(1 color(red)(cancel(color(black)("mol N"_2"O"_5))))#

#= 1.73 × 10^24 color(white)(l)"N"_2"O"_5color(white)(l) "molecules"#
