Chapter 11, Problem 11.64SP

Interpretation Introduction

Interpretation:

The required gram of nalorphine that are needed to obtain a dose of $\text{1}\text{.5}\text{mg}$ has to be calculated.

Concept introduction:

Molality of a solution also called as molal concentration can be defined as the mass of solute in grams to the mass of the solvent in kilograms. It can be given by the equation,

$\text{Molality(mol}{\text{kg}}^{\text{-1}}\text{)=}\frac{\text{Mass}\text{of}\text{solue(in}\text{g)}}{\text{Mass}\text{of}\text{solvent(in}\text{kg)}}$
