What is the weight of one gallon of water?

7.5 pounds
8.33 pounds
9.2 pounds
10.1 pounds

The correct answer is: 7.5 pounds

Water is commonly considered to have a weight of 8.33 pounds per gallon, so this may be a tempting answer choice. However, this weight can vary slightly based on temperature and the presence of impurities. Option B may also seem plausible based on its closeness to the universally accepted weight, but it is not the exact answer. Options C and D are further from the accepted weight and could be eliminated as they are not as commonly associated with the weight of water. Therefore, A is the most accurate answer.
