$A$ solution of sodium chloride with a concentration of ...... is isotonic with the fluid inside human red blood cells.

At $310 \ K$,the osmotic pressure of blood is $7.65 \ atm$. An aqueous solution of glucose will be isotonic with blood at a concentration of ........ $\%$ (weight/volume).

What is the osmotic pressure of a solution prepared by dissolving $3 \ g$ of solute in $2 \ dm^3$ of water at $300 \ K$ (in $atm$)? (Molar mass of solute $= 60 \ g \ mol^{-1}$,$R = 0.0821 \ dm^3 \ atm \ K^{-1} \ mol^{-1}$)

At $17^\circ C$,the osmotic pressure of an aqueous solution of sucrose $(C_{12}H_{22}O_{11})$ containing $34.2 \ g/L$ is $P$. What concentration of glucose $(C_6H_{12}O_6)$ in $g/L$ would be isotonic with this solution?

The process of getting fresh water from sea water is known as

$FeCl_3$ reacts with $K_4[Fe(CN)_6]$ in aqueous solution to give a blue color. These solutions are separated by a semipermeable membrane $(SPM)$ as shown in the figure. Due to osmosis,there is:
