There are 4 easy steps to find the molar mass of 4KMnO4 based on its chemical formula. 1. Count The Number of Each Atom The first step to finding the molar mass is to count the number of each atom present in a single molecule using the chemical formula, 4KMnO4: ElementNumber of Atoms...
Molar Mass (g/mol) K (Potassium) 1× 39.0983 = 39.0983 Mn (Manganese) 1× 54.938045 = 54.938045 O (Oxygen) 4× 15.9994 = 63.9976 4. Sum Each Element's Mass Finally, add together the total mass of each element to get the molar mass of KMnO4*nO: 39.0983 g/mol + 54.938045 g/mol ...
doi:10.1016/0144-8617(96)00009-4The weight average molar masses and molar mass distributions of three different preparations (identical in chemical composition, but different in the average degree of polymerization) of hydroxypropylmethyl cellulose have been characterized by SEC/MALLS (size exclusion ...

The use of size exclusion chromatography (SEC) for the determination of molar mass distribution and fractionation of coal tars has been investigated. The construction of a calibration graph based on typical components of the tars for use in the determination of molar mass distributions has revealed ...
