Chapter 2, Problem 64a
Solve each of the following problems using one or more conversion factors:
a. Wine is 12% alcohol by volume. How many milliliters of alcohol are in a 0.750-L bottle of wine?
Verified step by step guidance1
Step 1: Understand the problem. The wine is 12% alcohol by volume, meaning 12 mL of alcohol is present in every 100 mL of wine. You are tasked with finding the volume of alcohol in a 0.750-L bottle of wine.
Step 2: Convert the volume of wine from liters to milliliters. Use the conversion factor: 1 L = 1000 mL. Multiply 0.750 L by 1000 mL/L to express the wine volume in milliliters.
Step 3: Set up the proportion to calculate the volume of alcohol. Use the given percentage (12% alcohol by volume) as a conversion factor: 12 mL alcohol / 100 mL wine. Multiply the total volume of wine (from Step 2) by this conversion factor.
Step 4: Perform dimensional analysis to ensure units cancel appropriately. The milliliters of wine will cancel, leaving milliliters of alcohol as the final unit.
Step 5: Write the final expression for calculation: (Volume of wine in mL) × (12 mL alcohol / 100 mL wine). This will give the volume of alcohol in milliliters.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Alcohol by Volume (ABV)
Alcohol by Volume (ABV) is a standard measure used worldwide to quantify the amount of alcohol (ethanol) contained in an alcoholic beverage. It is expressed as a percentage, indicating the volume of alcohol per 100 milliliters of the beverage. For example, a wine with 12% ABV contains 12 milliliters of alcohol in every 100 milliliters of wine.

Volume Conversion
Volume conversion involves changing a measurement from one unit to another, such as liters to milliliters. In this context, it is essential to know that 1 liter equals 1,000 milliliters. This conversion is crucial for accurately calculating the amount of alcohol in a given volume of wine, as the problem specifies the wine's volume in liters.

Calculation of Alcohol Content
To calculate the alcohol content in a beverage, you multiply the total volume of the beverage by the percentage of alcohol by volume (ABV). In this case, to find the milliliters of alcohol in a 0.750-L bottle of wine with 12% ABV, you would convert the volume to milliliters and then apply the formula: (total volume in mL) x (ABV) = volume of alcohol in mL.
