Calculate the van't Hoff factor $(i)$ of a centimolar solution of potassium ferrocyanide $(K_4[Fe(CN)_6])$ if it is $60\%$ dissociated at $300\text{ K}$.

Which of the following $0.05 \ M$ aqueous solution will have the lowest freezing point?

Which of the following will have the highest boiling point at $1 \ atm$ pressure?

$A$ centimolar solution of acetic acid is $50 \%$ dissociated at $27^{\circ} C$. The osmotic pressure of the solution (in $atm$) is $\left(R=0.083 \ L \ atm \ K^{-1} \ mol^{-1}\right)$

When mercuric iodide $(HgI_2)$ is added to an aqueous solution of potassium iodide $(KI)$,the

The elevation in boiling point of a solution of $10 \ g$ of a binary electrolyte (of molecular mass $100$) in $100 \ g$ of water is $\Delta T_b$. Then,the value of $K_b$ for water is
