how much does 1 gallon of dehydrated water weigh?
396345
As much as the remaining impurities (plus the empy container, if you are putting that on the scale).

I liter of water weighs 1 kg so if the density of diesoline is say .9 then 1kg would weigh .9 kg... it depends on the density!!

gah!\n\nthis is the problem with yahoo answers.  lots of downright wrong information.\n\nthe gallon is a unit of volume.  it is 3.78 liters. \n\nmilk and paint have different densitities.  depending on the type of paint you use, you get different densitites - the chart in the page below shows the densities for various formulations of paint varies from 8.5 pounds per gallon to 12 pounds per gallon.  milk has a density of 8.4 pounds per gallon.  so the answer largely depends on what kind of paint you use - a gallon of very thin, light paint will probably weigh only a little more than a gallon of milk.\n\njust remember, a gallon of air is still a gallon.

1 cm3 of water equals 1 gram of water.\n1 gram of water equals 0.001 kilograms of water\nThus 455 cm3 = 0.455 kg (unlike the first answer you got)

1.0 imperial gallon = 4.55 liter = 1.20 US gallon

Looks like this is your homework. anyway, i'll only answer two of your questions.\n\n1. the density of water is almost 1 g/mL. and 1 liter = 1000 mL. hence the mass of 1 liter of water is 1000 g.\n\n2. since 1 liter of water is 1000 g or 1.00 kg, its weight is 1.00 * 9.8 = 9.80 N

i say its 50 to 1 thats 5ozs to one gallon

OK , i'll give it try.  we are assuming that the water is distilled because that affects the specific gravity.  grams per cc of h20.  4 oz. of water =1 cup......so 1oz of water =.0296 liters.......4 x that  = .1184 liters.....devide that by 1000 to get the mass or gram  value of 1.184 cubic centimeters = 1 cup of water...give me 10 pts for effort.!!  I think i messed up on the conversion but believe the answer is correct!

A minimum of 64 oz a day, but more is better. Don't drink it all at once, though. Hyponatremia ("water intoxication" or "water poisoning") can occur, but only if a large quantity of water is consumed in a short amount of time. Spread it out throughout the day, and you can drink a gallon easily.

1 gallon of water is approximately 3.8 liters and each litter is about 1 kg . So 1 gallon is 3.8 Kg. %5 of 3.8 is 190 gm. \nAnd you should add Acetic Acid, not Citric Acid.

1 gallon = 3.7854118 litres

An object sinks when it's weight exceeds the weight of the amount of water displaced by it's volume. The density of pure fresh water is 1kg/l. Assuming the the bottle must be completely full to contain 2l of water, a 2l bottle of water will weigh 2 kg and displace 2 kg. It will have neutral buoyancy. The bottle itself will displace more than it weighs, so the bottle will float.

dimensionally, volume is in units 1/(length)^3 and mass is in kilogrammes. So the mass of water is not strictly speaking equal to its volume. However, at standard temperature and pressure, 1 litre of water is equal to 1 kg of water. This is simply a definition (in the same way the temperature scale Celsius is 0C for freezing point and 100C for boiling point). So the reason why - is that it is defined as being equal; there is no particular physical reason for this.

The Imperial gallon (4.546 09 litres (L)) and bushel (36.368 72 L) are, respectively, 20% and about 3% larger than the United States liquid gallon (3.785411784 L) and bushel (35.23907016688 L). The Imperial gallon was originally defined as the volume of 10 avoirdupois pounds of water under specified conditions, and the Imperial bushel was defined as 8 Imperial gallons.\n\nAlso, the subdivision of the Imperial gallon as presented in the table of British apothecaries' fluid measure differed in two important respects from the corresponding United States subdivision, in that the Imperial gallon was divided into 160 fluid ounces (whereas the United States gallon is divided into 128 fluid ounces), and a "fluid scruple" is included.\n\nAs noted above, in the customary British system the units of dry measure are the same as those of liquid measure. In the United States these two are not the same, the gallon and its subdivisions are used in the measurement of liquids; the bushel, with its subdivisions, is used in the measurement of certain dry commodities. The U.S. gallon (3.785 411 784 L) is divided into four liquid quarts (946.352 946 mL each) and the U.S. bushel (35.239 070 166 88 L) into 32 dry quarts (1.101 220 942 715 L each) or 4 pecks (8.809 767 541 72 L each). All the units of capacity or volume mentioned thus far are larger in the Imperial system than in the U.S. system (by about 20% for wet measures). But the British fluid ounce is smaller than (about 96% of) the U.S. fluid ounce, because the British quart is divided into 40 fluid ounces whereas the U.S. quart is divided into 32 fluid ounces.\n\nFrom this we see that, in the Imperial system, an avoirdupois ounce of water at 62 °F has a volume of one fluid ounce, because 10 pounds is equivalent to 160 avoirdupois ounces, and 1 Imperial gallon is equivalent to 4 Imperial quarts, or 160 fluid ounces. This convenient relation does not exist in the U.S. system because a U.S. gallon of water at 62 °F weighs about 8 1/3 pounds, or 133 1/3 avoirdupois ounces, and the U.S. gallon is equivalent to 4 × 32, or 128 fluid ounces.\n\n\nComparison of Imperial and U.S. volume measures 1 U.S. fluid ounce = 29.573 529 562 5 mililitres ≈ 1.041 Imperial fluid ounces\n1 Imperial fluid ounce = 28.413 062 5 mililitres ≈ 0.961 U.S. fluid ounce\n1 liquid U.S. gallon = 3.785 411 784 litres ≈ 0.833 Imperial gallon\n1 Imperial gallon = 4.546 09 litres ≈ 1.201 liquid U.S. gallons\n1 dry U.S. gallon = 4.404 842 803 2 litres ≈ 0.968 Imperial gallon\n1 Imperial gallon = 4.546 09 litres ≈ 1.032 dry U.S. gallons

Well, you are talking a volume compared to a weight.\n\nA gallon of water weighs 8 pounds.

42 US liquid gallons. \n\nIt is only 36.09 US dry gallons, and 34.99 Imperial gallons. \n\nA dry gallon is related to the bushel, and is one eighth of a US dry bushel.

Weight times density yeilds volume. You need it's density before you can compute it's volume.\n\nOnly with materials (like water) where the specific gravity is 1(implying 1ml of water weighs one gram) are you able to convert fluid measurements to/from weight, without explicit multiplication/division.
