ppm is mg/L so 1.08e3ppm is 1.083e3mg/L. you can convert this to mole/L by simply converting the mg to grams then to mole using m/Mr where m is the mass in grams and Mr is the molar mass of Na (periodic table). once you get that, you will end up with a mol/L. Then you need to work out the volume of water using its density.
