Alcohol and ethanol

Question

You consume 25.0 mL of whiskey (47% alc by vol) and 27.5 mL of scotch (40% alc by vol). Which drink gave you the most ethanol? How many grams of ethanol did each drink yield? density of ethanol is 0.789 g/cm^3

Answer 1

CeeCee,

 

1mL=1cc

cc - cubic centimeter - cm^3

 

Whiskey has: 25mL*0.47 = 11.75mL = 11.75cc of ethanol i,e  11.75cc*0.789g/cc = 9.27g

 

Scotch (Whiskey?) has:  27.5mL*0.4 = 11mL = 11cc and that makes it : 8.68g of ethanol

 

 

47% = 47/100 = 0.47

40% = 40/100 = 0.40
