Hello, Taylor,
We're in luck due to a conversion factor that continues to amaze me. That is, at STP, all gases occupy a volume of 22.4 liters/mole. Only at STP, but it;s a very useful constant since the gas lws can convert to correct for non-STP conditions.
Take the mass of N2O5 and convert it to moles by dividing by it;s molar mass (I get 108.1 grams/mole. If we have the moles, and the gas is at STP, multiply by 22.4 liters/mole to get the volume, in liters, of dinitrogen pentoxide.

Way too many sig figs. Make that 36.5 liters (3 sig figs)
