If it isn't likely to work, it's bad right? Just checking. I noticed that you NaOH to nh4no2 ratio was backwards, you neeed twice as much ammonium nitrate to the amount of NaOH, by weight of course, which I highly suggest using weight. Also the amount of lithium is enough to over reduce your precursor, 2x amount, ok, 3x amount=over-reduction
I was off put by your prerequisite whining, whilst I assue looking for help. Yeah, there are a few problems in there. At least one is a terminal flaw (the lithium).
I would tell you more about it, but I don't want to come off as"whining about your methods", so, in light of that, I suggest you use the fucking search function to do some research, be less ambiguous on the rewrite and correct your math. I didn't look at the whole thing, but maybe I will next round.
