What will be the osmotic pressure of a $10\%$ sugar solution at $69\,^oC$ (in $, atm$)? (Molar mass of sugar $= 342 \, g/mol$)

If a $6.84 \% (wt./vol.)$ solution of cane sugar $(mol. wt. 342)$ is isotonic with a $1.52 \% (wt./vol.)$ solution of thiocarbamide,then the molecular weight of thiocarbamide is:

Isotonic solutions have the same

Which statement is wrong regarding osmotic pressure $P$,volume $V$,and temperature $T$?

$A$ $5\%(w/v)$ solution of sucrose is isotonic with a $1\%(w/v)$ solution of substance '$A$'. What is the molar mass of substance '$A$'?

If $20 \ g$ of a solute was dissolved in $500 \ mL$ of water and the osmotic pressure of the solution was found to be $600 \ mm$ of $Hg$ at $15 \ ^oC$,then the molecular weight of the solute is:
