What is unit conversion?
Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimeter is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
The weight of the cat is 8 lbs. Therefore, the weight of the cat in kg will be,
Weight of cat = 8 lbs = (8×0.454) kgs = 3.632 kgs
Since for one kg, the recommended dose is 5 mg, therefore, the recommended dose for the cat will be,
Recommended dose for cat = 3.632kg × 5 = 18.16 mg
Now, as given that one ml of solution contains 2mg of drugs, therefore,
1 ml = 2mg
1 mg = 1/2 ml
18.16 mg = 18.16 × 1/2 = 9.08ml ≈ 9 ml
Hence, the volume of the solution should be given to a cat that weighs 8 lbs. is 9 ml. Thus, the correct option is D.
