SUMMARY
The discussion centers on the equivalence of 1 ppm (parts per million) and 1 mg/L (milligram per liter) in aqueous solutions. The user presents conflicting equations regarding the definitions of ppm and mg/L, ultimately concluding that 1 ppm equals 1 mg/L when the density of water is assumed to be approximately 1 kg/L. The confusion arises from the interpretation of mass ratios and the conversion factors involved in these definitions.
PREREQUISITES
- Understanding of concentration units, specifically ppm and mg/L.
- Basic knowledge of mass and volume relationships in aqueous solutions.
