An aqueous solution containing $12\cdot50\text{ g}$ of barium chloride in $1000\text{ g}$ of water boils at $373\cdot0834\text{ K}$. Calculate the degree of dissociation of barium chloride. Given $K_b$ for $\text{H}_2\text{O} = 0\cdot52\text{ K kg mol}^{-1}$; molecular mass of $\text{BaCl}_2 = 208\cdot34\text{ g mol}^{-1}$
