Q)

# $\bar{M_N}$ of polymers is always determined by which of the following methods?

$\begin{array}{1 1}(a)\;\text{Light scattering}\\(b)\; \text{Osmotic pressure}\\(c)\;\text{ Sedimentation}\\(d)\;\text{Ultracentrifugation}\end{array}$

For synthetic polymers,$\bar{m_n}$ is always determined by employing methods which depend upon the number of molecules present in the polymer sample.For example,colligative property such as osmotic pressure is used.
