Calculating the Concentration in PPM (Parts per Million)

A concentration of 1 ppm 1 ppm can be written in the following ways. 1 ppm = 1 g 1 000 000 g = 1 g 1 000 kg = 1 mg 1 kg 1 ppm = 1 g 1 000 000 g = 1 g 1 000 kg = 1 mg 1 kg. When we have an aqueous solution at room temperature, we can also conclude that a concentration of 1 ppm 1 ppm corresponds to the following.
