Given information
The compounds of the buffer are 
and 
.
The pH of the buffer is 
.
The osmotic pressure of the buffer is 
.
The temperature of the buffer is 
.
Step-by-step explanation
Step 1.
A buffer solution is made up of a certain amount of weak acid and its conjugate base, or a certain amount of weak acid and its conjugate base.
When you add a buffer solution to an acid, the conjugate base in the buffer neutralizes it, and when you add a buffer solution to a base, the weak acid neutralizes it.
The Osmotic pressure is given by the formula,
Where,
is the osmotic pressure of the buffer.
is the concentration of in the buffer.
is the temperature of the buffer.
is the universal gas constant.
Now, Substitute the given values to the above expression:
Moles of 
(Molarity)(Volume)
Moles of 
Moles of 
The moles of in 
of solution is
