A typical IV used in hospitals is dextrose 5% in water (called D5W). This solution is injected into veins through an IV to replace lost fluids and to provide carbohydrates. Injectable medicines are also delivered to the body using the D5W IV. D5W contains 5.0 g dextrose monohydrate (C6H12O6・H2O) ‍‍‍ per 100.0 mL of solution. Assuming a density of 1.01 g/cm^3, calculate the molarity and molality of D5W.

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
