Nalorphine (c19h21no3), a relative of morphine, is used to combat withdrawal symptoms in narcotics users. how many grams of a 1.3 x 10-3 m aqueous solution of nalorphine are needed to obtain a dose of 1.5 mg?

3.7g

Explanation:

First we calculate the molar mass of the drug. Secondly, we now obtain the mass of the drug solution required at the given concentration to obtain a 1.5 milligram dose of the drug. The substitution is now properly done and the mass is obtained as 3.7g of the nalorphine drug which is a relative or morphine used to combat withdrawal symptoms in narcotic users.

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
