Determine the degree of association (polymerization) for the reaction in aqueous solution

$6 HCHO ⇌ C_{6} H_{12} O_{6}$

If observed (mean) molar mass of $HCHO$ and $C_{6} H_{12} O_{6}$ is 150:

Options:

Answer:

Solution:

$\begin{matrix} 6 HCHO & ⇌ & C_{6} H_{12} O_{6} \\ Conc. at equilibrium & C (1 - α) & \frac{C α}{6} \end{matrix}$

$\begin{array}{l} α = \frac{M_{T h} - M_{o b s}}{(n - 1) M_{o b s}} \\ = \frac{30 - 150}{[\frac{1}{6} - 1] 150} \\ = \frac{120}{\frac{5}{6} \times 150} = 0.96 \end{array}$
