Assume that all solution were prepared at 25℃, and the solutes were completely dissolved.
Alcoholic beverages are solutions. A certain brand of beer contains about 6.00% (v/v) of ethanol, while rum contains about 40.0% (v/v) ethanol. A group of college students are planning to host a party with what little money they have. They mixed 2 bottles of beer (500.0 mL per/bottle), a bottle of rum (350.0 mL), and some water to make a 2000.0 mL drink.
a. Compute 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 15.0 mL?
