Answer:

Well, first you have to specify a temperature and pressure......

Explanation:

And typically, we specify a temperature of #298*K#, and a pressure of #1*atm#. There are all sorts of these standards depending on the syllabus, and how childish your prof is......

The one I will use here is that an ideal gas occupies #25.4*L# under these conditions........

And thus #"moles of nitrous oxide"=(0.280*L)/(25.4*L*mol^-1)# #=# #0.0110*mol.........#

Of course we know that #1000*cm^3-=1.000*L#.....
