Which of the following pairs of solutions can be isotonic at the same temperature?

Osmotic pressure is $0.0821 \ atm$ at a temperature of $300 \ K$. Find the concentration in $mol/L$.

Calculate the temperature of $0.05 \ M$ sucrose solution in Kelvin if the osmotic pressure of the solution is $1.5 \ atm$. $[R = 0.0821 \ dm^3 \ atm \ K^{-1} \ mol^{-1}]$

At $298 \, K$,the ratio of osmotic pressures of two solutions of a substance with concentrations of $0.01 \, M$ and $0.001 \, M$ respectively,is
