To calculate the median lethal dose (LD50) in this population, we need to know the average weight of the population. Let's assume the average weight is 70 kg.
LD50 of caffeine = 480 mg/kg
Average weight of the population = 70 kg
To find the median lethal dose, we multiply the LD50 by the weight:
Median lethal dose = LD50 * Average weight
Median lethal dose = 480 mg/kg * 70 kg
Median lethal dose = 33,600 mg
Therefore, the median lethal dose of caffeine in this population would be 33,600 mg.
