Mountain Dew® contains caffeine, C8H10N4O2, at a concentration of 0.7838 mM and has a density of 0.998 g/cm3. (a) What is the concentration of caffeine in units of % by volume (w/v)? (b) What is the concentration of caffeine in units of % by mass (w/w)? (c) Compare you answers from (a) and (b). You should not be surprised if they are similar because % by mass and % by volume are the same if the density of the solution were exactly 1 g/cm3.

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.
