WebAccording to my Henderson's Dictionary of Biological Terms, dry weight is. The weight or mass of organic matter or soil after removal of water by heating to constant weight. So yes, your definition is correct and it is also applicable to cells. The dry weight of cells is the weight left when their water content has been removed by heating. WebThe so-called equilibrium moisture content is the content in the powder appropriate to every ambient gas humidity. The hygroscopic moisture content is determined by drying a sample to constant weight. This method is most widely used, but is not applicable to substances with decomposition or fusion temperatures below 110°C. laura wasson missouri
