Final answer:
To find the weight of the animal, we first calculated how many milliliters of the drug were administered based on the concentration (2.6 mL). Using the dose rate, we then determined that the animal weighs 39 kg.
Step-by-step explanation:
To determine how much the animal weighs, we first need to calculate the amount of drug administered per kilogram of the animal's weight. We are given that the animal is administered 26 mg of a drug, at a dose rate of 1 mL per 15 kg, and the concentration of the drug is 10 mg/mL.
First, find out how many milliliters of the drug were given to the animal:
Since the concentration is 10 mg/mL, the animal was given
26 mg ÷ 10 mg/mL = 2.6 mL of the drug.
Then, calculate the animal's weight by applying the dose rate:
Given the dose rate of 1 mL per 15 kg, and the animal received 2.6 mL, then:
Weight of animal = Dose rate (in kg/mL) × Amount of drug (in mL)
Weight of animal = 15 kg/mL × 2.6 mL = 39 kg
Therefore, the animal weighs 39 kilograms.
