5 gallon of water - 41.7pounds (lb), 18.9 kg

To calculate the weight of 5 gallons of water, we need to know the density of water and then use the formula:

Weight=Volume×DensityWeight=Volume×Density

1. Density of Water:

   • The density of water is approximately 8.348.34 pounds per gallon (lb/gal) or 11 kilogram per liter (kg/L).

2. Volume:

   • 1 gallon is approximately 3.785413.78541 liters.
   • 5 gallons would be 5×3.78541=18.927055×3.78541=18.92705 liters.

Now, let's calculate the weight:

1. In pounds (lb): Weight=5 gallons×8.34 lb/gal=41.7 pounds (lb)Weight=5gallons×8.34lb/gal=41.7pounds (lb)

2. In kilograms (kg): Weight=18.92705 liters×1 kg/L=18.92705 kilograms (kg)Weight=18.92705liters×1kg/L=18.92705kilograms (kg)

So, 5 gallons of water weighs approximately 41.741.7 pounds (lb) and 18.9270518.92705 kilograms (kg).
