If a solution has an osmotic pressure of $0.82 \ bar$ at $27 \ ^oC$,find the concentration of such a solution. (in $M$)

Which of the following colligative properties can provide the molar mass of proteins,polymers,and colloids with greater precision?

As a result of osmosis,what happens to the volume of the solution?

If a $0.1 \ M$ solution of glucose (mol. wt. $180$) and $0.1 \ M$ solution of urea (mol. wt. $60$) are placed on the two sides of a semipermeable membrane to equal heights,then it will be correct to say

$A$ $0.6 \%$ solution of urea (molecular mass $= 60$) would be isotonic with

$A$ solution is prepared by dissolving $0.6 \ g$ of urea (molar mass $= 60 \ g \ mol^{-1}$) and $1.8 \ g$ of glucose (molar mass $= 180 \ g \ mol^{-1}$) in $100 \ mL$ of water at $27 \ ^oC$. The osmotic pressure of the solution is : ............. $atm$ $(R = 0.08206 \ L \ atm \ K^{-1} \ mol^{-1})$
