Many common materials that we ingest, though quite safe in reasonable quantities, become toxic when taken in very large doses. A measure of toxicity is the LD 50 value (Lethal Dose, 50%). It is the quantity of material, expressed in mg of material per kg of subject-body-weight that, if administered to a population of subjects, would cause 50% of the population to die. The LD 50 value for FD&C Red Dye No. 40 is >10,000 mg/kg in rats. Assume that the LD 50 value for humans is the same as for rats. Calculate the number of mg of Allura Red present in an 12 fluid ounce glass of the beverage you used in this lab. Assume that the concentration of Allura Red in the beverage is 0.000034 M. The molar mass of Allura Red is 496.42 grams/mol 1 fl oz = 29.5735 mL

Calculate the number of number of glasses of Allura Red sports drink, each containing 8.8 mg of Allura Red, required to reach the LD 50 of 10,000 mg of Allura Red/kg body weight. Assume the person has a body weight of 165 lbs. 2.205 lbs 1 kg !! You may assume two significant figures but do not use sčientific notation. Do not include units with your answer. Your Answer: Answer
