It depends on the reason for use:
As a long term anticoagulant or preventative measure for heart disease the standard dose is 81mg per day. This is a baby aspirin dose. This will vary depending on the medical professionals evaluation of the patient. And you should be evaluated first. Research during 2013-2014 showed that daily aspirin may not help all patients and can create harmful effects.
As a painkiller for adults the recommended dose is 1-2 tablets every 4-6 hours which is 275-300mg. Not exceeding 3 doses per day. Do not use if you are on any other anti-coagulants such as Warfarin, or have had a stomach ulcer in the past 12 months. For people who smoke and drink, the chances of stomach bleeding, a rare side effect, is increased.
For Children, it is half that dose MAXIMUM. Do not use to treat symptoms of chicken pox as it may cause a fatal side effect called Reye's syndrome, a rare but possible side effect of Aspirin.
Pregnancy:
Aspirin should NOT TO BE USED DURING PREGNANCY AS HIS MAY CAUSE FETAL DAMAGE, ESPECIALLY IN THE LAST TRIMESTER.

that's not true, in fact magnesium sulfate has been tested on rats and dogs, and it does have an ld50. "The LD50 values were 206 mg/kg for males and 174 mg/kg for females"

LD50 relates to the compound/element, not to poisoning - it is the LD50 of mercury. It varies depending on route of exposure and the animal tested but it is around 1 to 15 mg/kg body-weight.
563 mg or about 0.8 milliliters.
The LD50/50 (50% mortality in 50 days) for strontium-90 in rats is estimated to be around 2.5 to 3 microcuries per gram of body mass. I do not know if that translates linearly to humans.
by definition ld50 is when 50% survive or dead,,answer will be 5 if i count well
ld50 for lamotrigine

LD50 (short for lethal dose 50) is the dose of a substance at which it kills 50% of test subjects.
The radiation LD50 of most insects is far higher than the LD50 of mammals.

A probable value for plutonium is LD50 = 5 μg/kg (cumulated chemical and radiological effects).
true,however LD50 just provide coarse idea and specific adverse effect also need be considered.
