$A$ $5\% \text{ (w/v)}$ solution of cane sugar (molar mass = $342 \text{ g/mol}$) is isotonic with a $1\% \text{ (w/v)}$ solution of an unknown solute. What is the molar mass of the unknown solute in $\text{g/mol}$?

Explain: What is osmosis? Give examples.

If $250 \ cm^3$ of an aqueous solution containing $0.73 \ g$ of a protein $A$ is isotonic with one litre of another aqueous solution containing $1.65 \ g$ of a protein $B,$ at $298 \ K,$ the ratio of the molecular masses of $A$ and $B$ is..........$\times 10^{-2}$ (to the nearest integer).

In which of the following pairs of solutions,separated by a semipermeable membrane,will the phenomenon of osmosis take place?

$0.5 \ M$ $P_3Q_2$ $(i = 5)$ and $0.01 \ M$ $M_2N_3$ $(i = 5)$ are separated by a semipermeable membrane $AB$ in an aqueous solution as shown. These solutes react to give a brown color. Due to osmosis,there is:

The solution in which the blood cells retain their normal form is with regard to the blood:
