What is the molarity, molality and mass percentage of this beverage ? Note that alcohol (ethanol) has a density of 0.789 grams per cubic centimeter and a molar mass of 46 g/mol. The values for water are 1 g/cm3 and 18 g/mol. Assume water and alcohol are the only contents of the beverage, and their volume is additive, if they are mixed (both is not strictly true in reality).
