A solution contains two isomers, n-propyl alcohol and isopropyl alcohol, at 25°C. The total vapor pressure is 38.6 torr. What ar
Leona [35]

Answer:

Mole fraction of alcohols in liquid phase x_1=0.2727\& x_2=0.7273.

Mole fraction of alcohols in vapor phase y_1=0.1468\& y_2=0.8516.

Explanation:

The total vapor pressure of the solution = p =38.6 Torr

Partial vapor pressure of the  n-propyl alcohol =p^{o}_1=21.0 Torr

Partial vapor pressure of the isopropyl alcohol =p^{o}_2=45.2 Torr

p=x_1\times p^{o}_1+x_2\times p^{o}_2  (Raoult's Law)

p=x_1\times p^{o}_1+(1-x_1)\times p^{o}_2

38.6 Torr=x_1\times 21.0 Torr+(1-x_1)\times 45.2 Torr

x_1=0.2727

x_2=1-0.2727=0.7273

x_1\& x_2 is mole fraction in liquid phase.

Mole fraction of components in vapor phase y_1\& y_2

p_1=y_1\times p (Dalton's law of partial pressure)

y_1=\frac{p_1}{38.6 Torr}=\frac{p^{o}_1\times x_1}{38.6 Torr}

y_1=\frac{21.0 Torr\times 0.2727}{38.6 Torr}=0.1468

y_1=\frac{p_2}{38.6 Torr}=\frac{p^{o}_2\times x_2}{38.6 Torr}

y_2=\frac{45.2 Torr\times 0.7273}{38.6 Torr}=0.8516

Mole fraction of alcohols in vapor phase y_1=0.1468\& y_2=0.8516

Recall rem = rad x q radiation weighting factor (q): the ability to transfer energy to the body 1 for photons 1 for electrons 2
tino4ka555 [31]

The biological risk for the first person than the second as a result of radiation weighting is 10 times.

<h3>What is radiation weighting factor?</h3>

As stated in the question, radiation weighting factor (q) is the ability to transfer energy to the body.

If radiation factor of proton = 2, and radiation factor of alpha particles = 20.

  • First person is exposed to alpha radiation = 20
  • Second person is exposed to protons = 2

Risk of first person with respect to second person = 20/2 = 10 times higher
