How much water makes one gallon?

Answer 1

It isn't 1+1 because the salt (some or all) will dissolve in the water. You cannot predict the volume. It needs to be measured experimentally, but the volume will certainly be less than 2 gallons.

Answer 2

At 20oC , 35.89 g NaCl (salt) dissolves in 100 g H2O (water) in order to make the solution saturated. I found this information using an online solubility table.

1 gallon is about 3.78 liters. Also, every liter weighs 1 kilogram. So one gallon of water is 3.78 kilograms or 3,780 grams.

(35.89 g NaCl) / (100 g H2O) = (x g NaCl) / (3,780 g H2O)

x=1,356.642 g

1.356 kg of salt makes one gallon of water saturated.

Answer 3

One gallon is equal to 128 fluid ounces or approximately 3.78 liters of water.

Answer 4

about two gallons to the gallon. but that's just a guess.

Answer 5

it depends where the salt water is coming from

Answer 6

gallon is a measure of volume.

one gallon of anything including water is still one gallon of that same thing.

Answer 7

pure water will dissolve 3.184 pounds of salt.

Answer 8

A gallon of salt water.

Answer 9

how much salt will one gallon of water dissolve

Answer 10

1 + 1 = 2
