Calculate the vapor pressure at 25 ?c of hexane above the solution. the vapor pressure of pure hexane at 25 ?c is 151 torr.
Studentka2010 [4]
One of the many ways in order to solve for the vapor pressure of pure components at a given temperature is through the Antoine's equation which is written below,
                                    P = 10^(A - B/C+T)
where A, B, and C are constants and T is the temperature in °C and P is the vapor pressure in mm Hg. 
For hexane,
                             A = 7.01
                             B = 1246.33
                             C = 232.988

Substituting the known values,
                            P = 10^(7.01 - 1246.33/232.988+25)
                             <em> P = 151.199 mm Hg</em>

mario62 [17]

Answer:

627.4 mmHg

Explanation:

From Gay-Lussac law:

\frac{p1}{t1}  =  \frac{p2}{t2}

p1 = 760 mmHg

t1 = 343 K

t2=283.15 K

p2 = p1 \times  \frac{t2}{t1}

p2 = 760 \times  \frac{283.15}{343.0}

p2 = 627.4 \: mmhg
