What is the numerical value of osmotic pressure of $1 \ M$ urea solution if the numerical value of osmotic pressure of $0.5 \ M$ urea solution is $x$?

$A$ solution containing $8.6 \ g$ of urea per liter is isotonic with a $0.5\% \ (w/v)$ solution of a non-volatile organic solute. What is the molar mass of the organic solute?

The osmotic pressure of a decinormal solution of $BaCl_2$ in water is

Solutions $A, B, C$ and $D$ are respectively $0.2 \ M$ urea,$0.10 \ M$ $NaCl$,$0.05 \ M$ $BaCl_{2}$ and $0.05 \ M$ $AlCl_{3}$. All solutions are isotonic with each other except:

Which of the following is the correct order of osmotic pressure for solutions containing equal moles of glucose,$NaCl$,and $BaCl_2$?

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
