a solution of C2H6O ethanol molar mass is 46.07 g / mol in water can be used to disinfect. A liter of this solution contains 533g of ethanol and 355. of water 18.02 g / mol. What is the lolar fraction of ethanol in this solution.
A certain alcoholic beverage contains only ethanol (C2H6O) and water. When a sample of this beverage undergoes combustion, the ethanol burns but the water simply evaporates and is collected along with the water produced by combustion. a. A 9.8959 g sample of this beverage is cured for elemental analysis in excess oxygen and 2.1104 g of CO2 is collected. How many moles of ethanol, C2H6O are in this sample? b. What is the % volume of ethanol for this beverage.
