How do you convert ppm in g per km?

Answer 1

To convert parts per million (ppm) to grams per kilometer (g/km), you can use the formula:

[ \text{g/km} = \text{ppm} \times \frac{\text{mass of the substance}}{\text{mass of the solution}} \times \frac{1 \text{ km}}{1,000,000 \text{ g}} ]

Assuming a 1 kg mass of solution (1,000 g), the conversion simplifies to:

[ \text{g/km} = \text{ppm} \times 0.001 ]

Thus, for every 1 ppm, you have 0.001 g/km.
