The relationship between pressure and solubility of the gas is given by Henry's law as:
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,
To convert 
to 
:
Molar mass of benzene, 
= 
Now for converting into 
:
Since, 
So, 
.
Hence, the solubility of benzene in water at 
in is 
.
The answer is 14.22 mg / (mm^2)
Answer: It is exhibiting retrogade motion.
When two plates push against each other shear stress will happem because they move in opposite directions. In this case the force of the stress pushes some of the crust in different directions. When this happens, a large part of the crust can break off, which makes the plate size smaller.
The correct answer is A. Alkali metals.
