In this paper a novel method is proposed for estimating number-average molecular weight from the intrinsic viscosity and GPC chromatogram of a sample for which the constants in Mark-Houwink equation is not known.The method was tested on seven samples which have very different value of molecular weight and molecular weight distribution.Results calculated by the method are in good agreement with those obtained using conventional method which requires constants of Mark-Houwik equation. The method is ijust approximate but fairly simple for number-average molecular weight determination
