The amount of dissolved sodium and chloride in seawater determine its?

Hi Ashley

I can try and help a bit, but they don't like it when we straight out give the answers here, OK?

To start, what is sodium and chloride when they combine?

Once you answer that and you imagine this product dissolved in water you may be able to figure out what the dissolved sodium and chloride are a measure of in seawater... ;)

You'll also want to look at the PHYSICAL PROPERTIES OF SEAWATER, OK?
