Calculating Vapour Pressure of Ethyl Alcohol
Given:
Mole fraction of ethyl alcohol (Xethanol) = 0.6
Vapour pressure of the mixture (Pmixture) = 290 mm
Vapour pressure of propyl alcohol (Ppropyl) = 200 mm
To find: Vapour pressure of ethyl alcohol (Pethanol)
Formula used:
Dalton's Law of Partial Pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the individual gases in the mixture.
Thus, Pmixture = Pethanol + Ppropyl
Also, mole fraction of a component is given by:
Xethanol = nethanol / (nethanol + npropyl)
where nethanol and npropyl are the number of moles of ethanol and propyl alcohol present in the mixture respectively.
Solution:
Let's first calculate the mole fraction of propyl alcohol:
Xpropyl = 1 - Xethanol = 1 - 0.6 = 0.4
Now, using the mole fraction, we can write:
nethanol = Xethanol * ntotal
npropyl = Xpropyl * ntotal
where ntotal is the total number of moles of both alcohols present in the mixture.
We can rearrange these equations to get:
ntotal = nethanol / Xethanol = npropyl / Xpropyl
Substituting the values, we get:
ntotal = nethanol / 0.6 = npropyl / 0.4
or, nethanol = 0.6 * ntotal and npropyl = 0.4 * ntotal
Now, using Dalton's Law of Partial Pressures, we have:
Pmixture = Pethanol + Ppropyl
or, 290 mm = Pethanol + 200 mm
or, Pethanol = 90 mm
Therefore, the

Now, using Dalton's Law of Partial Pressures, we have:

or, Pethanol = 90 mm
Therefore, the
