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.

Three liquid samples of known masses are heated to their boiling points with the use of a heater rated at 500.0 W. Once the boiling points of each sample are reached, the samples are heated for an additional 4.96 min, which results in the vaporization of some of each sample. After 4.96 min, the samples are cooled and the masses of the remaining liquids are determined. The process is performed at constant pressure. The results are recorded in the table.
