How do scientists actually calculate the lethality of poisons?

Question

For example, I read that 5g of cyanide is enough to kill 35 people. What does that even mean? If I could somehow split 5g of solid cyanide (is that a thing?) into 35 parts and put it in 35 peoples’ Dr. Pepper they would all die? And how could you possibly test that?
