At 300 K temperature, Beaker A containing 0.02 M solution of urea and Beaker B containing 0.002 M solution of sugar are separated by semipermiable membrane with repsect should be applied to prevent osmosis ? Molecular weight of urea = 60 g / mol and molecular weight of sugar = 342 g / mol. [R=0.082" L atm. mol"^(-1)k^(-1)]

Answer»

0.4428 ATM. on BEAKER B
0.4920 atm. on beaker A
0.4920 atm. on beaker B
NONE of the above

SOLUTION :`pi=CRT`
`=0.02xx0.082xx300`
= 0492 atm. on beaker A
