Under which condition a 5% solution of glucose will be isotonic with a 4% solution of an organic substance at same temperature ?

Define 'osmosis' and 'osmotic pressure'. Show that osmotic pressure is a colligative property. A 4% solution of sucrose (C_12 H_22 O_11) is isotonic with 3% solution of an unknown organic substance. Calculate the molecular mass of the unknown substance.

A 5% solution of cane sugar (M. wt = 342) is isotonic with 1% solution of substance X. The molecular weight of X is:

A 0.6% solution of urea (Mol.mass = 60) would be isotonic with:

A 5% aqueous solution of sucrose is isotonic with 3% aqueous solution of another substance ‘A’. find molecular mass of A. (sucrose mol. mass=342)

A solution containing 8.6 g urea in one litre was found to be isotonic with a 5% (wt./vol.) solution of an organic non-volatile solute. The molecular weight of latter is:

The concentration of glucose (in g/litre)solution which is isotonic with a solution of urea containing 6 g per litre will be:

A 4% solution of sucrose (C_(12) H_(22) O_(11)) having mol mass 342 is isotonic with 3% solution of an unknown organic substance . Calculate the molecular mass of the unknown substance.
