Question

which relation osmotic pressure is related to molar mass of solute​

Answer 1

Answer:

the osmotic pressure method has a advantages over the method as pressure measurement is around room temperature and the molarity of the solution is used instead of molarity as compared to their qualitative properties its magnitude as a large even for their duty solution

Answer 2

Osmotic pressure is inversely proportional to molar mass of solute.

Explanation:

• Osmotic pressure is the minimum pressure applied to prevent the entry of solvent through semipermeable membrane. The equilibrium hydrostatic pressure of column set up as a result of osmosis.
• Osmotic pressure is represented by 'π' and π  is directly proportional to no. of moles of solute and it is directly proportional to mass of solute and inversely proportional to molar mass of solute.
• So osmotic pressure is also inversely proportional to molar mass of solute. We can prove it by using equations as given below,

⇒  $\pi \propto N_2$

$\pi$ is osmotic pressure and $N_2$ is the no. of moles of solute.

No. of moles of solute is,

⇒  $N_2=\frac{W_2}{(MM)_2}$

$W_2$ is the mass of solute and $(MM)_2$  is the molar mass of solute.

so the osmotic pressure is,

⇒  $\pi \propto W_2$        --(1)  

⇒  $\pi \propto \frac{1}{(MM)_2}$        --(2)

Equation (2) proves that osmotic pressure is inversely proportional to molar mass of solute.
