Final answer:
The mass of alcohol in Brad Pitt's three bottles of mixture that has a total mass of 1488 grams and is 25.6% alcohol by mass, is 381 grams.
Step-by-step explanation:
Brad Pitt has three bottles of alcohol/water mixture with a total mass of 1488 grams, and the mixture is 25.6% alcohol by mass. To find the total grams of alcohol present in the mixture, you can use the following calculation:
Total mass of mixture = Mass of alcohol + Mass of water
Knowing that the mixture is 25.6% alcohol by mass, we can calculate the mass of alcohol as follows:
Mass of alcohol = 25.6% of 1488 grams
Mass of alcohol = 0.256 × 1488 grams
Mass of alcohol = 380.928 grams
The closest answer to 380.928 grams is 381 grams, so the correct answer is (d) 381 grams.
