How much alcohol for it to be lethal?

[wtg]

I have a 500ml bottle of vodka, will it be enough to kill me?

No. I mean, you could try partial hanging while being drunk. That's probably better.

If you ingest it orally than you will almost certainly throw up any meaningful amount or pass out unless you are an alcoholic - which I guess you are not if you are asking about a small bottle of vodka

LD50 of ethanol (alcohol) is 5-7g/kg. You would need to drink at least 2 Liters of vodka (assuming you weigh 100kg and the vodka is 40%). Even if you don't throw up (which you will if you tried to drink this much) it's not guaranteed that you will die. I'm not even gonna go into the damage you would do to yourself if you attempt this way and fail.

Depends on your weight and metabolism, if you are able to chug 1l of vodka and keep it in your stomach then it could be lethal. People accidentaly die from chugging bottles for show. Not easy though.
