The first one is B because it’s gonna be positive if it’s gaining energy
The relationship between pressure and solubility of the gas is given by Henry's law as:
![S_g = kP_g](https://tex.z-dn.net/?f=S_g%20%3D%20kP_g)
where,
is the solubility of the gas.
is proportionality constant i.e. Henry's constant.
is pressure of the gas.
(given)
(given)
Substituting the values,
![S_g = 5.6 bar/mol/kg\times 0.13 bar = 0.728 mole/kg](https://tex.z-dn.net/?f=S_g%20%3D%205.6%20bar%2Fmol%2Fkg%5Ctimes%200.13%20bar%20%3D%200.728%20mole%2Fkg)
To convert
to
:
Molar mass of benzene,
= ![6\times 12+6\times 1 = 78 g/mol](https://tex.z-dn.net/?f=6%5Ctimes%2012%2B6%5Ctimes%201%20%3D%2078%20g%2Fmol)
![0.728\times 78 = 56.784 g/kg](https://tex.z-dn.net/?f=0.728%5Ctimes%2078%20%3D%2056.784%20g%2Fkg)
Now for converting into
:
Since, ![1 ppm = 0.001 g/kg](https://tex.z-dn.net/?f=1%20ppm%20%3D%200.001%20g%2Fkg)
So,
.
Hence, the solubility of benzene in water at
in
is
.
Answer:

Answer:
A) 0.95 mol
Explanation:
We will assume the gas given off in the fermentation is an ideal gas because that allows us to use the ideal gas equation.
PV = nRT
First let's convert all measurements to units that we can use
P = 702 mmHg * 1 atm/760 mmHg = 0.92368 atm
V = 25.0 L
R = 0.08206 L-atm/mol-K
T = 22.5 °C +273.15 = 295.65 K
PV = nRT
0.92368 atm * 25.0 L = n * 0.08206 L-atm/mol-K * 295.65 K
n = 0.9518 mol
