What is the weight of 100 gallons of water?

The weight of water can be calculated based on its density, which is approximately 8.34 pounds per gallon. To find the weight of 100 gallons of water, you multiply the number of gallons by the weight per gallon:

100 gallons x 8.34 pounds/gallon = 834 pounds.

This calculation shows that the weight of 100 gallons of water is approximately 834 pounds. Therefore, the correct answer is identified as 830 pounds, which closely aligns with this calculation when considering rounding or slight variances in measurements.

Understanding this calculation helps in various practical applications, such as in agriculture, where knowing the weight of water can inform decisions about irrigation systems and pesticide application methods.
