A solution which is composed of heptane (C-H16, 100.198 g mol"") and octane (CH43, 114.224 g mol-) has vapor pressure of 78 torr at 40 °C. The saturated vapor at equilibrium with the solution contains 16.55 g heptane and 22.15 g octane. The vapor pressures of pure heptane and pure octane at 40 °C were 92.0 Torr and 31.2 Torr, respectively. What is the mole percent of CH18 in the initial solution? Do not write units, only enter numerical values. Use two digits at most for decimal numbers, use dot (.) as decimal separator (i.e. two-point-fifty-one should be entered as 2.51). Do not use comma (,) as decimal separator.

Concept explainers

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.
