Solutions having the same osmotic pressure under a given set of conditions are known as

The $pH$ of a $0.2 \ M$ aqueous solution of a dibasic acid $(H_2A)$ is $1.699$. Its osmotic pressure at $T \ K$ is ......... $RT$.

The osmotic pressure of a solution increases,if:

Calculate the osmotic pressure of a solution prepared by dissolving $1.75 \ g$ of glucose $(C_6H_{12}O_6)$ in $150 \ mL$ of solution at $17 \ ^oC$. (in $atm$)

$A$ solution containing $10 \ g$ of urea (molar mass $= 60 \ g \ mol^{-1}$) per liter is isotonic with a $5 \% \ w/v$ solution of a non-volatile solute. The molar mass of the non-volatile solute is ......... $g \ mol^{-1}$.

$A$ $1\% \ (wt/vol) \ KCl$ solution is ionised to the extent of $80\%$. The osmotic pressure at $27 \ ^oC$ of the solution will be .......... $atm$.
