If the elevation in boiling point of a solution of $10 g$ of solute $(mol . wt = 100)$ in $100 g$ of water is $Δ T b$ , the ebullioscopic constant of water is

Options:

Answer:

Solution:

$m = \frac{1000 \times k _{b} \times w}{W \times Δ T _{b}}$ or $k_{b} = \frac{m \times W \times Δ T _{b}}{1000 \times w} = \frac{100 \times 100 \times Δ T _{b}}{1000 \times 10} = Δ T_{b}$
