At 300K temperature Beaker A containing 0.02M solution of urea and Beaker B containing 0.002M solution of sugar are seperated by SPM with respect to water . On which Beaker how much pressure should be applied to prevent osmosis?

osmotic pressure is given by the formula,pi=CRT
where C is the concentration of the solution
R is the gas constant
T is the temperature in kelvin
osmotic pressure in each beaker separated by semi permeable membrane
beaker A=CRT=.02*.0821*300=.49 bar
beaker B=.002*.0821*300=.049 bar
