Solution for Sea water contains an average of 1.08 x 10³ ppm of Na* and 270 ppm of SO,". Calculate a. the molar concentrations of Na* and SO, given that the …

1) Unless specified otherwise, ppm usually refers to ppm by weight: 2.89 ppm = 2.89 g per 1,000,000 g (or any other weight unit, I have just chosen g for convenience) 2) Now you need to know the density of the solvent to convert the volume to mass. If the solvent is water, we can assume the density at standard temperature and pressure is 1.0 g/mL.

Sea water contains an average of 1.08x103 ppm of Na+ and 270 ppm SO42-. Calculate the molar concentrations of Na+ and SO42- given that the density of sea water is 1.02 g/ml. Since tap water ranges widely. If you use water filters in your home, you can expect the PPM to be lower than unfiltered water. Water quality can range due to a number of factors like the age and material used for the pipes.
