An aqueous solution containing $12\cdot48\text{ g}$ of barium chloride ($\text{BaCl}_2$) in $1000\text{ g}$ of water, boils at $100\cdot0832^\circ\text{C}$. Calculate the degree of dissociation of barium chloride. ($K_b$ for water = $0\cdot52\text{ K kg mol}^{-1}$, at. wt. $\text{Ba} = 137$, $\text{Cl} = 35\cdot5$)
