If you measure it by filling a graduated glass column, you obtain the volume of the salt plus the volume of the air between the salt crystals. This measured value is NOT the volume of the salt. The volume of the salt cannot be measured. It must be calculated from the mass and the density. | |

| Jan 12, 2023 at 5:21 | comment | added | roman m | @ToddMinehardt forget the experiment, how much should the water volume go up if I add 50ml of salt to 500ml of water? Is there a reference table for something like this? I'd expect there to be one. | |

| Jan 12, 2023 at 5:13 | comment | added | roman m | @ToddMinehardt I guess the error was that instead of 50ml of salt I've added 37ml, which makes the result even closer. As I've said, I used food measuring cups, so volumes are not too precise, that's why I've used weight to keep me honest. Bottom line, water volume went up by roughly the amount of salt added. I'm sure you have salt and water handy, give it a go. | |
| Jan 12, 2023 at 1:25 | comment | added | Todd Minehardt | With the density of NaCl at 2.16 g/cc, 50 ml should weigh 108 g. Bottom line is there is an error on your part somewhere. | |
