Wine is 12 % (by volume) alcohol. How many milliliters of alcohol are in a 0.750- L bottle of wine?
lorasvet [3.4K]
In this question, you are given the wine/alcohol concentration (12%) and the volume of the alcohol(0.75l). You are asked the alcohol content in milli liters, so don't forget to change the unit. Then the equation would be:

Alcohol content= alcohol concentration * bottle volume
Alcohol content = 12%* 0.75l * 1000ml/l= 90ml
