. A sample of an ethanol-water solution has a volume of 52.5 cm³ and a mass of 49.6 g. What is the percentage of ethanol (by mass) in the solution? (Assume that there is no change in volume when the pure compounds are mixed.) The density of ethanol is 0.789 g/cm³ and that of water is 0.998 g/cm³. Percentage of ethanol = b. Alcoholic beverages are rated in proof, which is a measure of the relative amount of ethanol in the beverage. Pure ethanol is exactly 200 proof, a solution that is 50% ethanol by volume is exactly 100 proof. What is the proof of the given ethanol-water solution? proof Submit Answer % [References] Try Another Version 10 item attempts remaining
