Question

the osmotic pressure of a solution containing 50g of a solute in one liter of solution at 300k is 20.5 atmosphere pressure. calculate molecular mass of solute ​

Answer 1

Explanation:

π=CRT=

V

(

Mw

2

W

2

)RT

Given W

2

=40g

Mw

2

=246

T=27

o

C=300K

V=1 L

Substituting all the values, we get

π=

1

246

40

×0.082×300

=4 atm
