    You need a balanced chemical equation for this. Does it specify what the N205 reacts with?

    N2O5 = H2O -> 2HNO3

    Okay, this is actually really simple. All you need is the mole/mole ratio (which you have in the equation) and the molar mass of each substance, which you get from a periodic table. Find the mass of N2O5, which is 108.01 g/mol, and HNO3, which is 63.01. Set up the equation \[0.65g N _{2}O _{5}^{?}(\frac{ 1 mol N _{2} O _{5}}{ 108.01 g })(\frac{ 2 mol HNO _{3} }{ 1 mol N _{2} O _{5} })(\frac{ 63.01 g HNO _{3} }{ 1 mol HNO _{3}}) = \] and solve.

    Oops, ! accidentally added grams of HNO3. Forget that last parenthesis section and you should get 0.012035922 mol HNO3, which you would probably only keep two significant figures of, so 0.012 mol.
