By studying the elevation in boiling point of an aqueous solution of glucose,the value of $K_b$ for water is found to be $0.51 \ K \ kg \ mol^{-1}$. What value of $K_b$ can be expected from an aqueous solution of $K_4[Fe(CN)_6]$?

For a $1 \ m$ (molal) aqueous solution of glucose,which of the following is correct?

Give the unit for the molal elevation constant in boiling point.

The boiling point of water $(100\,^{\circ}C)$ becomes $100.52\,^{\circ}C$,if $3\,g$ of a non-volatile solute is dissolved in $200\,mL$ of water. The molecular weight of the solute is: (${K_b}$ for water is $0.6\,K\,kg\,mol^{-1}$)

If the boiling points of two solvents $X$ and $Y$ (having same molecular weights) are in the ratio $2 : 1$ and their enthalpies of vaporization are in the ratio $1 : 2$,then the boiling point elevation constant of $X$ is $\underline{ m }$ times the boiling point elevation constant of $Y$. The value of $m$ is $.....$. (Nearest integer)

The normal boiling point of ethyl acetate is $77^{\circ}\text{C}$. $A$ solution of a non-volatile, non-electrolyte solute in ethyl acetate boils at $78^{\circ}\text{C}$. The $K_b$ for ethyl acetate is $2.77^{\circ}\text{C kg mol}^{-1}$. What is the molality of the solution (in $\text{ m}$)?
