That depends on how much water you are talking about. Do you have a drop, a pint, a gallon, a swimming pool's worth, or an ocean's worth? I'm not trying to be a wise-ass, but I see your question -- or some form of it -- about a hundred times a month, and it shows a basic misunderstanding of mass, weight, and density. I suggest you check out this topic and all its questions and answers to get a better idea of the difference between those three characteristics of matter. Chances are you really wanted to know the weight of fresh water per unit volume. In other words, you want to know how much a gallon of water weighs, or perhaps you want to know how much a cubic meter of water weighs. That's called density. A US gallon weighs 8.33 pounds. Its density, therefore, is 8.33 pounds per gallon. If you go to Google calculator, you can easily convert that to grams per milliliter or ounces per fluid ounce, kilograms per liter, or kilograms per cubic meter -- whatever!
A gallon of water weighs approximately 8.34 pounds (3.78 kilograms) at room temperature.
Correct formulation: "How much does a stone weigh in salt water?"Answer: The same as it does in the air, water, anywhere.
Only about 10 of the water that evaporates from a salty ocean is fresh water.
50 oz of water would weigh approximately 3.13 pounds.
100 liters of water would weigh approximately 100 kilograms, as the density of water is 1 kg/liter.
They can weigh up to 200 pounds.
Roughly 72 pounds.
That would depend on the temperature and is this fresh or sea water? About 305.72
15.8 ounces
A gallon of water weighs approximately 8.34 pounds (3.78 kilograms) at room temperature.
The same as above the water. Lead is a dense metal and has no bouyancy at all.
A gallon of fresh water is heavier than a gallon of sea water because fresh water is denser than sea water.
It depend upon how much it contains.
I don't know how much salinity is in fresh water.
3% of the earths water, is fresh water
3% is fresh, but 1% is for drinking.
