Answer #1

ANSWER- 0.4ML OF DEMEROL

EXPLANATION- Since the required amount of drug dose is mentioned, that is 40mg. And each ml of drug contains 100mg of drug.

we can cross multiply to get the answer. that is to, multiply 40mg of demerol drug with 1ml of demerol, and divide this whole by 100mg of demerol, we get 0.4ml of demerol drug.

so, 0.4ml of demerol drug will have 40mg of the drug.

GOOD LUCK!
