To calculate the parts per million (ppm) of NaI in a 500 g sample of a bottle of water, we need to know the mass of NaI present in the sample.

Let's say that we perform an analysis and determine that the mass of NaI in the sample is 0.25 g.

We can then use the following formula to calculate the parts per million of NaI in the sample:

ppm = (mass of NaI / mass of sample) x 10^6

Substituting the values we have:

ppm = (0.25 g / 500 g) x 10^6

Simplifying:

ppm = 500

Therefore, the parts per million of NaI in the 500 g sample of the bottle of water is 500 ppm.
