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>
Answer is: fatty acids of short (C4-C6) and medium (C8-C10) chain fatty acids (SCFAs and MCFAs) solubilize in intestinal fluids and are absorbed directly into the portal system.
Fatty acid with ten carbon atoms made medium chain triglycerides, that we also consume by food and get energy by breaking bonds between and oxidizing carbon atoms.
Answer:
7.35 atm
Explanation:
From the question we are given;
- Initial volume, V1 as 28 L
- Initial temperature, T1 as 42°C or 315 K
- New volume. V2 as 49 L
- New temperature, T2 as 27°C or 300 K
- New Pressure, P2 as 4.0 atm
We are required to determine the initial pressure, P1
We are going to use the combined gas law...
According to the combined gas law,

Therefore, to get P1

We get;


Therefore, the initial pressure of the gas is 7.35 atm
