1. Hydrogen bonds occurs to Hs attached to an electronegative atom (N, O or F) 
2. Structure appears to have 1 N with 1 lone pair, 2 Os with 2 lone pairs and 1 O with 3 lone pairs
3. Each lone pair is capable of accepting 1 H-bonds; hence it can accept 8 H bonds
4. For the Hs attached to N or O; the total of number of Hs is 5 Hs
5. 5 Hs attached to N can do H-bond
