Osmotic pressure can be calculated using the following equation:
Here,
C representated concentration
R represented gas constant
T represented temperature
representated osmotic pressure
R=0.0821 atm L mol ⁻¹
T = 25 + 273 = 298 K
C=
Given mass of the substance= 6.00 g
Volume= 1 L
=0.75 atm
Putting all the values in the equation:
Molar mass of the substance= 195 g mol⁻¹.

Explanation:
<em>Distillation is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components in the mixture. In either case, the process exploits differences in the relative volatility of the mixture's components. In industrial applications, distillation is a unit operation of practically universal importance, but it is a physical separation process, not a chemical reaction.</em>
Solution :
<u>Explanation 1 </u>:
Spontaneity of the reaction is based on two factors :
-- the tendency to acquire a state of minimum energy
-- the energy of a system to acquire a maximum randomness.
Now, since there isn't much difference in the bond enthalpies of B-F and B-Cl. So, we can say the major driving factor is tendency to acquire a state of maximum randomness.
<u>Explanation 2 </u>:
A system containing the B halides has a than a system of and .
It has the same number of , but more distinguishable kinds of , hence, more microstates and higher entropy.
