The mass of substance consumed in g to provide a lethal dose is 62.496 g
The substance has an LD50 of 336 mg/kg. We require the number of grams of the substance that a 186 kg person would consume to reach the probable lethal dose.
So, mass of substance consumed = lethal dose × mass of person
lethal dose = 336 mg/kg and mass of person = 186 kg
mass of substance consumed = lethal dose × mass of person
mass of substance consumed = 336 mg/kg × 186 kg
mass of substance consumed = 62496 mg
Converting to g, we have
mass of substance consumed in g = 62496 mg × 1 g/1000 mg = 62.496 g
So, the mass of substance consumed in g to provide a lethal dose is 62.496 g
