depends on the liquid. One gallon of gasoline would be very different from one gallon of mercury
depends on the density?
As a liquid, it weighs 12.2 pounds per gallon.
A gallon is a unit of measurement used for liquid, and is not applicable to solid substances, e.g rocks.
Depends on the liquid. Gallons measure volume, kilograms measure weight. A gallon of water does not weigh the same as a gallon of gasoline. Different liquids have different densities.
2350lbs. on average
A gallon is a measure of, usually, liquid volume. A gallon of water is 128 ounces. Other liquids will weigh more or less depending the specific gravity.
that would vary based on the density of the liquid being measured
The amount of dry ounces in one gallon is going to be dependent on what liquid is being weighed in the gallon. For example, a gallon of water is going to weigh less than a gallon of oil.
1 gallon of water weighs 8.3333 pounds. However, the weight depends upon the specific gravity of the liquid you are measuring.
