You drink a 12 oz beer that has 4.5% ABV. The rest of the calories, other than alcohol, come from carbohydrates. If the beer contains 140 calories, how many calories from carbohydrates did you ingest<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

To calculate how many calories from carbohydrates you ingested, we first need to break down the total calories in the beer. The beer contains 140 calories, and we are told that the alcohol (ABV) contributes to some of these calories. The remaining calories come from carbohydrates.<\/p>\n\n\n\n

Step 1: Calculate Calories from Alcohol<\/h3>\n\n\n\n

The alcohol content in the beer is 4.5% ABV. This means that 4.5% of the volume of the beer is pure alcohol. To find the calories from alcohol, we use the fact that one gram of ethanol (alcohol) contains approximately 7 calories.<\/p>\n\n\n\n

Step 1a: Find the amount of alcohol in the beer.<\/h4>\n\n\n\n
    \n
  • The beer is 12 oz, which is approximately 355 mL (since 1 oz \u2248 29.57 mL).<\/li>\n\n\n\n
  • 4.5% of the beer’s volume is alcohol, so: 355\u00d70.045=15.975\u2009mL\u00a0of\u00a0alcohol.355 \\times 0.045 = 15.975 \\, \\text{mL of alcohol}.355\u00d70.045=15.975mL\u00a0of\u00a0alcohol.<\/li>\n<\/ul>\n\n\n\n

    Step 1b: Convert alcohol volume to grams.<\/h4>\n\n\n\n
      \n
    • The density of ethanol is about 0.789 g\/mL. 15.975\u2009mL\u00d70.789\u2009g\/mL=12.61\u2009g\u00a0of\u00a0alcohol.15.975 \\, \\text{mL} \\times 0.789 \\, \\text{g\/mL} = 12.61 \\, \\text{g of alcohol}.15.975mL\u00d70.789g\/mL=12.61g\u00a0of\u00a0alcohol.<\/li>\n<\/ul>\n\n\n\n

      Step 1c: Calculate calories from alcohol.<\/h4>\n\n\n\n
        \n
      • Since each gram of alcohol provides 7 calories, the calories from alcohol are: 12.61\u2009g\u00d77=88.27\u2009calories\u00a0from\u00a0alcohol.12.61 \\, \\text{g} \\times 7 = 88.27 \\, \\text{calories from alcohol}.12.61g\u00d77=88.27calories\u00a0from\u00a0alcohol.<\/li>\n<\/ul>\n\n\n\n

        Step 2: Calculate Calories from Carbohydrates<\/h3>\n\n\n\n

        Now, we subtract the calories from alcohol from the total calories in the beer to find the calories from carbohydrates.<\/p>\n\n\n\n

          \n
        • Total calories = 140 calories<\/li>\n\n\n\n
        • Calories from alcohol = 88.27 calories 140\u221288.27=51.73\u2009calories\u00a0from\u00a0carbohydrates.140 – 88.27 = 51.73 \\, \\text{calories from carbohydrates}.140\u221288.27=51.73calories\u00a0from\u00a0carbohydrates.<\/li>\n<\/ul>\n\n\n\n

          Conclusion<\/h3>\n\n\n\n

          You ingested approximately 51.73 calories<\/strong> from carbohydrates in the beer.<\/p>\n\n\n\n
