Nalorphene `(C_(19)H_(21)NO_(3))`, similar to morphine, is used to combat
withdrawl symptoms in narcotic users. Does of nalorphene generally
given is 1.5 mg. Calculate the mass of `1.5xx10^(-3)m` aqueous solution
required for the above does.

Explanation

To solve the problem, we need to calculate the mass of a 1.5 x 10^(-3) molar (M) aqueous solution required to provide a dose of 1.5 mg of nalorphene (C₁₉H₂₁NO₃). Here’s how we can do this step by step:

### Step 1: Convert the dose from mg to grams
The dose of nalorphene is given as 1.5 mg. We need to convert this to grams for easier calculations.

\[ \text{Dose in grams} = \frac{1.5 \text{ mg}}{1000} = 0.0015 \text{ g} \]
