How much should 500ml of water weigh ?

[tampon]

Is it as a woman I am having a arguement with says it is, 500g, or is that mixing too different measurements becuase they look the same ?

Room temperature etc, just a rough idea

[Antwerpman]

0.5kg

[carrera2]

500g.

[Jinx]

1 Litre of water equals approximately 1 kg.

this woman you are arguing with, did she type your post too?

ps - 1ml = 1g

[mr_tony]

1 cubic centimetre of water at room temp should weigh (for all intents and purposes) 500g.

1 litre weighs 1kg.

I'm sure things vary slightly - especially if you play with temperature and pressure - but for everyday purposes the above holds...

everyone knows that

WAIT! YOU CAN STILL WIN THIS ARGUMENT!!!



Tell her it weighs 0.5N. That'll piss 'er right off.



Edited for being mathematically retarded.

Well, to be pedantic, one litre of water has a mass of 1kg, and a weight of 9.86 Newtons.

I'm sure it would weigh the same if it were in a plane on a conveyor belt, but if you nuked it from orbit it would clearly weigh more...... or perhaps less!

I didn't

Different density liquids will obviously be different, but water at standard temperature and pressure should be 1ml = 1g. If you're talking about a solution containing a dissolved compound then it will be different, but pure H2O is 1ml = 1g

[Mr E]

At 1bar and 4 degrees C, distilled water should mass damn close to 1Kg a litre.

What it weighs depends on the pull of gravity.....

Science pedant, I know.

500g did not equal 5000N when I was at school, 0.5 x 9.81 = 4.905 rings a bell though.

[JonRB]

I'm sure that OrgasmicLiving will be along shortly to explain why it is not 500g and that it won't take off even if thrown forcefully against his head via a high-speed conveyor belt, but the fact of the matter is that 1L of water at room temperature and pressure (RTP) masses 1kg which in normal earth gravity means it weighs approx 1kg.

Shut up

[limegreennutter]

5000N - that's roughly 1/2 tonne!!!

[sleep envy]

was she right then?

IIRC 1N = 100g

[Pickled Piper]

I litre of water has a mass of 1kg always because that is how a litre is defined.

ignore the facts or the actual point of the arguement, i bet, without doubt, she was right
