First thing is to check if your stoichiometric equation is balanced. 
Next, set up a plan (that usually helps me see the plan or route i'm taking) and write down the information given.

GIVEN: 0.65 grams $N_2O_5 $
WANT: moles of $HNO_3 $

So, the set up is: 0.65 grams of $N_2O_5 \rightarrow $ moles of $N_2O_5 \rightarrow $ moles of $HNO_3 $ 

If you remember from your algebra course, it's very similar to fractions in the sense tha tyou're just canceling out units to get the desired units.
