The value of osmotic pressure of a $0.2 \ M$ aqueous solution at $293 \ K$ is ........... $atm$.

In case of osmosis,solvent molecules move from:

$A$ $25 \%$ solution of cane-sugar (molar mass $= 342 \ g \ mol^{-1}$) is isotonic with a $5 \%$ solution of a substance $A$. Find the molecular weight of $A$.

During osmosis,the flow of water through a semipermeable membrane is:

The pressure required for the reverse osmosis is quite high. For this,which of the following membranes is used?

When $10 \ g$ of glucose $(P_1)$,$10 \ g$ of urea $(P_2)$,and $10 \ g$ of sucrose $(P_3)$ are dissolved in $250 \ mL$ of water,what is the relationship between their osmotic pressures at $273 \ K$?
