There are two water-ethanol solutions at 15°C and 1 atm, thefirst one has an ethanol molar fraction of 0.09000 and a density of0.96576 . The second has a mole fraction of ethanol of0.1000 and a density of 0.96281 . Calculate:
a) The weight percentage of each solution.
b) for the water-ethanol solution at 15°C and 1 atm, which willbe at 21.1% by weight of ethanol. Since the change in thecomposition of the solution is small, the following expression canbe used:
