Benzene and toluene form ideal solutions. Consider a solution of benzene and toluene prepared at 25∘C. As suming that the mole f

ractions of benzene and toluene in the vapor phase are equal, calculate the composition of the solution. At 25∘C the vapor pressures of benzene and toluene are 95 and 28 torr, respectively.

Answer:

Xtoluene = 0.77

Xbenzene = 0.23

Explanation:

Step 1: Data given

Temperature = 25.0 °C

the mole fractions of benzene and toluene in the vapor phase are equal

At 25∘C the vapor pressures of benzene and toluene are 95 and 28 torr.

Step 2:

Xtoluene + Xbenzne = 1

Since the mol fractions are equal, the partial pressure also will be equal.

pToluene = pbenzene

Xtoluene *pToluene = Xbenzene *pBenzene = (1.00 - Xtoluene)*pBenzene

⇒with X toluene = mol fraction of toluene

⇒pbenzene = vapor pressure benzene = 95 torr

⇒Xbenzene = mol fraction benzene = 1.0 -0.5

⇒ptoluene = 28 torr

Xtoluene * 28 torr = (1.0 - Xtoluene)*95 torr

Xtoluene = 0.77

Xbenzene = 1.0 - 0.77 = 0.23

Based on the molar masses, how can you tell that an equation is balanced?
Ilya [14]
When you work with molar mass, you solve for the quantity of ''Moles'' within the substance by converting Mass. The way you can tell the equation is balanced would be by knowing whether the moles were equivalent on both sides or not. Therefore, if they are equal, it is balanced considering you have the same amount of moles on each side of the equation.
