2 g of a non-volatile non-electrolyte solute is dissolved in 200 g of two different solvents A and B whose ebullioscopic constants are in the ratio of 1 : 8. The elevation in boiling points of A and B are in the ratio ${x \over y}$ (x : y). The value of y is ______________. (Nearest integer)
Answer (integer)
8
Solution
$\Delta T b=k b m$
<br/><br/>
$$
\begin{aligned}
&\frac{\left(\Delta T_{b}\right)_{A}}{\left(\Delta T_{b}\right)_{B}}=\frac{\left(k_{b}\right)_{A}}{\left(k_{b}\right)_{B}} \\\\
&=\frac{1}{8}=\frac{x}{y} \\\\
&\therefore y=8
\end{aligned}
$$
