Osmotic pressure of $0.1 \ M$ aqueous solution of $MgCl_2$ at $300 \ K$ is $4.92 \ atm$. What will be the percentage ionization of the salt? $.......... \ \%$

At $300 \, K$,$36 \, g$ of glucose present in a litre of its solution has an osmotic pressure of $4.98 \, bar$. If the osmotic pressure of the solution is $1.52 \, bar$ at the same temperature,what would be its concentration?

$A$ solution is made by dissolving $20 \ g$ of a substance in $500 \ mL$ of water. Its osmotic pressure was found to be $600 \ mm$ of $Hg$ at $15 \ ^oC$. The molecular weight of the substance is

The relationship between osmotic pressure at $273 \ K$ when $10 \ g$ glucose $(P_1)$,$10 \ g$ urea $(P_2)$,and $10 \ g$ sucrose $(P_3)$ are dissolved in $250 \ mL$ of water is:

Isotonic solutions are solutions having the same

For a very dilute solution of an electrolyte,which of the following relations is correct? (Assume other parameters are constant)
