Solve the following problems and show complete solutions. The final answers must be reported in proper units and number of significant figures. Assume that all solutions were prepared at 25°C, and the solutes were completely dissolved. Molar masses should be based on the Periodic Table provided. Density values are provided if needed. Alcoholic beverages are solutions. Typically, a beer contains about 4.50% (v/v) of ethanol fermented by yeast from sugars, while a particular soju brand contains about 24.0% (v/v) ethanol. A Korean-inspired drink was prepared by mixing 500.0 mL of beer with 200.0 mL of the soju. The mixture was finally diluted to 750.0 ml using enough cola. 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 25.0 mL? DENSITY VALUES AT 25°C Ethanol: 0.789 g/mL Acetic Acid: 1.05 g/mL Water: 0.997 g/mL

the solutes were completely dissolved. Molar masses should be based on the Periodic Table provided.
Density values are provided if needed.
Alcoholic beverages are solutions. Typically, a beer contains about 4.50% (v/v) of ethanol
fermented by yeast from sugars, while a particular soju brand contains about 24.0% (v/v)
ethanol.
A Korean-inspired drink was prepared by mixing 500.0 mL of beer with 200.0 mL of the soju. The
mixture was finally diluted to 750.0 mL using enough cola.
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 25.0 mL?
