Weight of cubic yard of water please

It is. Until the water is saturated (and the salt starts piling up on the bottom, displacing water), the volume of the water the salt is dissolved in doesn’t measurably change …

Thank you.

DSYoungEsq: Don’t be too hard on yourself. Explaining things intelligably is tough.

That is not true at all, IIRC my chemistry. While the total volume of the two components will be greater than the volume of the mixture, it is incorrect to assert that the solvent will displace no volume.

Keep in mind that solutions don’t have to be liquid…

That’s it. Once again one is astonished about the blessings of the metric system:

1 liter = 1 cubic decimeter = 1/1000 cubic meter = 1000 cubic centimeters

Mass (approximateley, notwithstanding differences according to temperature etc): 1 kilogram
