Question

13) Find the osmotic pressure in mm of
Hg at 15°C of a solution of naphthatene
(CH) in benzene containing 14 gm
of napthalene per lit. of solution.​

Answer 1

Answer:

$\pi = w \times rt \div m \times v$

T=15°c=15+273

m=128g/mol (C10H8)

w=14g

v=1L

R=0.0821L atm /mol/k

(14×0.0821×288)/(1×128)=1965.47×760mm Hg
