Alcoholic beverages are solutions. Typically, a beer contains about 4.50% (v/v) of ethanol fermented by yeast from sugars, while a paticular soju brand contains about 2.4% (v/v) ethanol. A korean-inspired drink was prepared by mixing 500.0 mL beer with 200.0mL of soju. The mixture was finally diluted tp 750.0mL using enough cola. a. Computes the final concentration (%w/v) of ethanol in the drink. b. How much of the drink (in mL) must a person take all at once so that the amount of ethanol ingested is 25.0mL?
