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.....
