The term PPM stands for "parts per million." Chemists use this notation to describe the concentrations of things that are diluted. To make it a percentage, 1 PPM is equal to 0.0001%.

What is the chemical shift for aromatic region in nuclear magnetic resonance spectroscopy?
It's around 7-8 ppm.
What is more toxic 3 ppm or 0.03 ppm?
A chemical with a toxic level of 0.03 ppm is more toxic because heavy metals with high density are toxic to organisms at low concentrations. In other words, it only took 0.03 ppm of the chemical to kill an organism, while the other chemical would have to take up to 3 ppm in order to kill the same organism. Which one is more toxic?
How much chemical would make 200 ppm?
The amount of chemical to make 200 ppm depends on the final volume of the solution. If you had 1 liter, then it would take 200 mg of chemical (0.2 grams). If you had a lake or a pond, it would take a lot more, and you'd need to know the volume of the lake or the pond.
What is 200 ppm ratio mixture of liquid chemical to quantity of water?
35:1
What is 4 ml of chemical added to 1liter of water in many ppm concentration?
4ml/1000 = approx 4000 ppm, depending on the final volume after adding 4ml to 1000 ml water
If 16 ounces of a chemical solution in 5 gallon of water equal 500 ppm how many ounces of chemical are needed to make one gallon?
3.2 ounces of chemical solution
What is the safe COD level for drinking water?
Between 50 ppm and 300 ppm is safe. Better below 100 ppm.
What is the definition of lead-free paint?
