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

$6 \text{HCHO} \rightleftharpoons \text{C}_{6} \text{H}_{1 2} \text{O}_{6}$

If observed (mean) molar mass of $\text{HCHO}$ and $\text{C}_{\text{6}} \text{H}_{\text{12}} \text{O}_{\text{6}}$ is 150:

$\alpha=\frac{\mathrm{M}_{\mathrm{Th}}-\mathrm{M}_{\mathrm{obs}}}{(\mathrm{n}-1) \mathrm{M}_{\mathrm{obs}}}$
$ = \, \, \frac{30 - 150}{\left[\right. \frac{1}{6} - 1 \left]\right. 150} \\ \\ = \, \, \frac{120}{\frac{5}{6} \times 150}=0.96 \\ $
