WebJan 1, 2010 · Soaking PMMA-coated microscope slides in 70% ethanol for 1 h was found to remove the PMMA coating (Figure 2, left panel), likely due to the solubility of PMMA in 80 wt% ethanol 13, therefore ... WebAnswer (1 of 3): In 100 g of alcoholic bourage, 50 g ethanol and 50 g water are present. Number of moles of ethanol,n1 = mass/molar mass = 50/46 = 25/23. Number of moles of water, n2 = 50/18 = 25/9. Mole fraction of ethanol = n1/(n1+n2) = (25/23)/{(25/23) + (25/9)} = 0.28125. Hope, this helps. WebWhen boiling an ethanol-water azeotrope, the boiling point of 100% pure ethanol can never be reached since the 96/4 mixture boils first. By adding benzene (warning: toxic!) 100% pure ethanol can be produced, since the benzene forms an azeotrope with the water, which can then be extracted.
