# How much does...

...a cubic meter of salt water weigh? This is not a spam post. I really want to know. My dad will pay me if I can tell him and I really need the money.

WELLLLLLL....

A cubic meter is 100x100x100 cubic centimeters...1,000,000. 1 cubic centimeter of water is 1 gram, but this is salt water. Unfortunately, I believe the weight would depend on the concentration of the salt water. Even if I knew that I wouldn't be able to tell you...

With the info provided I don't see that you can get an exact answer.

O.K. thanks for trying to help me anyway.

Ask andrew.. Maybe this will be the first question on these boards that he can't answer....

Does anyone here know what is the area of a gallon milk jug is in cubic centimeters?

A cubic meter of salt water weighs 2,259.84 pounds. Don't know 'bout the milk jug.

------------------

Wouldn't how much it weighs depend one the waters density, e.g salt water from the dead sea would way more than saltwater from the atlantic ocean.

Never mind. I found out the answer.

The weight of a cubic metre of water would depend upon where you got your cubic metre of water. At the bottom of the sea, where the pressure is much higher, you'd get a hell of a lot of water molecules into the same space... so the question is flawed.

Another tiny flaw is that weight (as opposed to mass) is dependent upon the gravity field in which you find your cubic metre. I'm assuming you meant on Earth...

Liquids do not compress. A given volume of liquid will have the same mass at any pressure.

They do, to a certain extent - it's just that you need a lot of pressure. Such as you find at the bottom of the ocean, or well down in Jupiter's core.

how concentrated is the salt water?
is it at sea level
and a whole lot of other variables
