How much does 100 gallons of water weigh?

To determine the weight of 100 gallons of water, it's essential to understand that water has a specific weight. One gallon of water weighs approximately 8.34 pounds. Thus, to find the total weight of 100 gallons, you would multiply the weight of one gallon by 100.

Calculating this:

100 gallons × 8.34 pounds/gallon = 834 pounds.

Rounding this result typically gives you 830 pounds. This means that the correct answer, which indicates the weight of 100 gallons of water, is indeed 830 pounds. Understanding this conversion and multiplication is crucial for solving similar problems in physics or chemistry, where liquid weights and volumes are frequently involved.
