Question

a solution of sucrose (molecular mass 342u) is prepared by dissolving 6.84g in 100g water at 298k.calculate the osmotic pressure of the solution at 298k ( density of water at 298k=1gmL-1)​

Answer 1

Answer:

The solution is 4.48 atm.

Explanation:

Osmotic pressure (π)=CRT

Here, C= concentration of solution

C=

V

n

∴n=

m

w

=

Mol. weight of substance

weight in gram of substance

V=1 litre

C=

342

68.4

π=

342

68.4

×0.082×273

=4.48 atm
