The viscosities of a series of solutions of polystyrene in toluene were measured at $25C$ and the results obtained are summarized below in Table $1.$ Determine the molecular weight of this polymer. The Mark$-$Houwink$-$Sakurada constants for this system are $K=7\mathrm{.}4810-4100m\frac{L}{g}$ and $=0\mathrm{.}75$
