How much does a gallon of ice weigh
Answers:
To greatly simplify, a chunk of ice placed in a lab at 0 degrees C and standard atmospheric pressure weighs roughly 0.9167 g/ml. If we assume that you are referring to a standard US gallon at one atmospheric pressure at sea level, we will have a 3.47kg mass of ice, which weighs 3.47kg (7.65 pounds).
(At 4 degrees C, water weighs 1.000 g/ml by definition. A standard US gallon of water at 4 degrees C weighs 3.79 kg or 8.35 pounds).
A gallon of snow will weigh much less than a gallon of solid ice -- see the "How many pounds does one gallon of snow weigh?" question.
By the way: a gallon is a measure for liquid quantities. At 0 degrees Celsius or above, ice becomes water, until it reaches 100 degrees Celsius, at which it vaporizes to become steam. Therefore, you can't really measure a "gallon" of ice. And it would freeze in a gallon container and break the container anyway.

That depends if it's a gallon of melted ice cream, or solid ice cream in a gallon sized tub. Ice cream often has loads of air added to it so they can sell less of it to the customer.
Depending of the liquid and the density of this liquid. Mass = volume X density
A gallon of brine weighs more than a gallon of water, but how much more it weighs than a gallon of water depends on how much salt was added to the water.
It depends on the specific gravity of the solution which in turn depends on the concentration of caustic material (gm/lire) and type of caustic material.
Bromine has a specific gravity of 194.800208 pounds per cubic foot. Therefore, one U.S. gallon weighs 26.040988 pounds.
