Median Lethal Dose using Therapeutic Index Solution

Follow our step by step solution on how to calculate Median Lethal Dose using Therapeutic Index?

FIRST Step Consider the formula
LD50=(ED50⋅TI)
Next Step Substitute values of Variables
∴ LD50=(20mg⋅8)
Next Step Convert Units
∴ LD50=(2E-5kg⋅8)
Next Step Prepare to Evaluate
∴ LD50=(2E-5⋅8)
Next Step Evaluate
∴LD50=0.00016kg
LAST Step Convert to Output's Unit
∴LD50=160mg
