Octane (CH) has a vapor pressure of 14.3 torr and a density of 0.703 g/mL. Benzene (CH) has a vapor pressure of 105.0 torr and a density of 0.876 g/mL. Assuming a mixture of the two behaved ideally and followed Raoult's Law, what would you predict to be the vapor pressure (in torr) of a solution containing 655 mL of octane and 555 mL of benzene?

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.
