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.

9.14 The density of a methanol-water solution that is 12.000 weight percent methanol is 0.97942 g/cm³ at 15°C and 1 atm. For a solution that is 13.000 weight percent methanol, the den- sity is 0.97799 g/cm³ at this T and P. Since the change in solu- tion composition is small, we can estimate VA by 3 VA = (aV/ana)r.P.ng - (AV/Ana)r.P.na (av/anA)T.P.na II Calculate V(CH,OH) for a methanol–water solution at 15°C and 1 atm that is 12,% CH,OH by weight.
