Estimating blood alcohol content (BAC) accurately requires more information than just the person's weight and the amount of alcohol consumed. Factors such as gender, metabolism, tolerance, and food intake also play significant roles. Therefore, it's not possible to provide a precise estimate without considering these factors. However, generally speaking, consuming two 12-ounce beers and 1 1/2 oz. shots of liquor within an hour can lead to a significant increase in BAC, especially for someone weighing 140 pounds. It's advisable for individuals to drink responsibly and be aware of their own limits.
