Thank you for the answers. To sum it up, if if I dissolved 684g of salt into 1316g of near-boiling water, it would be roughly 34.2% salt. Correct?

https://www.sciencedaily.com/terms/seawater.htm but from this article, it says that the ocean has a salinity of 3.5%, and it says that means 35 parts-per-thousand. I'm not sure that I understand? and this article says that there'd be around 250g of salt left if you boiled a liter of dead sea water. http://www.sciencefocus.com/qa/how-much-salt-there-dead-sea

For demonstration purposes, (to float things on) I am bringing two tubs of water to my presentation - one with the salinity of normal water, and one with that of the Dead Sea. From my understanding, since the dead sea is 34.2% salt, if I mixed 684g of salt with 2kg of distilled water, would that accurately represent the water in the Dead Sea?
