Column and Thin Layer Chromatography Beverly Abstract: Plant pigments were separated and concentrated from a crude spinach extract through the use of column chromatography and an eluatropic series of hexanes‚ hexane/acetone‚ and methanol. The pigments were analyzed using thin layer chromatography with a 30% ethyl acetate/hexane developing solvent. Introduction: Chromatography is a technique used to separate a mixture of two or more components based on

Objective:- The aim of this experiment was to find the molar mass of unknown volatile liquid under known temperature and pressure. Introduction Molar mass or gram molar mass is the mass of the substance under consideration without distinguishing whether a substance is an element ‚ a molecule or an ionic compound. These elements‚ molecules or ionic compound could be solid gas or liquid. The molar mass of gas or vapor could be measured if the gases obey the law of Ideal Gas . The mass of
