Saline is 9 g of salt per 1 kg of water. what ppm is this?

Density of water is 1 kg/L

There is 9 g of salt per 1 kg of water, on converting mass of water into its volume, there will be 9 g of salt per litre of water

1 ppm is equal to mg per litre

Since,  1 mg = 0.001 g

Thus, 1 ppm is equal to 0.001 g per litre

1 g/ l will be

Therefore, 9 g/l =

Hence, concentration of saline in water is 9000 ppm.
