What is the osmotic pressure $(\pi)$ of a $0.02 \ M$ solution of $NaCl$ (in $RT$)?

Which method is used to remove salt from sea water?

Which of the following can pass through a semi-permeable membrane?

Find out the osmotic pressure of a $0.2 \, M$ solution of glucose at $300 \, K$. (in $, \text{atm}$)

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 $g$)

$18 \ g$ glucose (Molar mass $= 180 \ g/mol$) is dissolved in $100 \ mL$ of water at $300 \ K$. If $R = 0.0821 \ L \ atm \ K^{-1} \ mol^{-1}$,what is the osmotic pressure of the solution (in $atm$)?
