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

She has a can of aerosol spray that is advertised at 500ml, and the can weighs 485 grams without the lid ( they all do, so it is not just one can that has been used ), so she has been undersold hasn't she.

aerosol spray

as always the clue is in the question

does this aerosol contain solely water?

No it is a fabric protector spray, would that make a difference, could a 500ml spray weigh less than than 0.5kg ?

????????????????????????????????????????
Dear god my head hurts

So there is a chance that they 500ml can could weigh less and still have 500ml in it ?
