The osmotic pressure $(\pi)$ of a polymer sample at different concentrations $(\mathrm{c})$ was measured at T(K). A plot of $(\pi / \mathrm{c})$ versus c gave a straight line with slope (m) and intercept (c'). The number average molecular weight of the polymer is ( $\mathrm{R}=$ gas constant).

(a)$\frac{\mathrm{Rt}}{\mathrm{c}^{\prime}}$

(b)$\frac{\mathrm{c}^{\prime}}{\mathrm{RT}}$

(c)RT
