Question

A solution has an osmotic pressure of 0.821 atm at 300 k. Its concentration would be:

Answer 1

Answer:

C= 0.003333333 moles per litre

Explanation:

Osmotic Pressure(Π) is given by :

Π= CRT

(where C is concentration ,R is gas constant , T is temperature )

given , Π = 0.0821 atm

T = 300K

then using above equation ,

C = 0.0821÷ (0.0821×300) mole per Litre

C= 0.003333333 moles per litre
