Question

A diagram of a U tube for measuring osmotic pressure is shown below. The height different between the two columns of liquid is 10.00 Cm. The dashed line represent a semi-permeable membrane through which solvent molecules can pass, but solute molecules can not.

i) On which side (right or left) is the solute located?

ii) Calculate the osmotic pressure in atmospheres. Hint this is actually easy: The pressure difference is given by pgH. Where p is the density of the solution. You can assume it is 1.000 grams per cm3 . g is the acceleration due to gravity, 9.8 M/S2 and H is the difference in height. Be Careful of Units

iii) Calculate the concentration of the solute.

Explanation / Answer

the solute molecules located in right side

osmotic pressure = pgh

=1000*9.8m/s*h

the cncentration will be calculated using molar concentration of desired materal.
