When the pure solvent diffuses out of the solution through the semi-permeable membrane,then the process is called:

In an osmosis process,the volume of the solution:

Assume a living cell with $0.9 \% (\omega / \omega)$ of glucose solution (aqueous). This cell is immersed in another solution having equal mole fraction of glucose and water. (Consider the data up to the first decimal place only). The cell will :

Calculate the amount of solute dissolved in $3 \ dm^3$ water having osmotic pressure $0.3 \ atm$ at $300 \ K$. (Molar mass of solute $= 108 \ g \ mol^{-1}, R = 0.0821 \ atm \ dm^3 \ K^{-1} \ mol^{-1}$) (in $g$)

Determine the amount of $CaCl_2$ $(i=2.47)$ dissolved in $2.5 \ L$ of water such that its osmotic pressure is $0.75 \ atm$ at $27^{\circ}C$.

Pickles have a long shelf life and do not get spoiled for months,why?
