WebSolimini (2005) reported an underestimation of dry mass for mayies in ethanol of approximately the same magnitude. In contrast, Dermott and Paterson (1974) noticed an increase in the percentage of dry mass, with the highest values observed for larvae when the preservative uid was dried. In gen-eral, the main reasons for the decreased mass of ... WebFor example, ethanol, with a molecular weight (MW) of 46, has a boiling point of 78 °C (173 °F), whereas propane (MW 44) has a boiling point of −42 °C (−44 °F). Such a large difference in boiling points indicates that molecules of ethanol are attracted to one another much more strongly than are propane molecules.
