Parts per million (ppm) is a measure of concentration that is used where low levels of concentration are significant. The ppm value is equivalent to the absolute fractional amount multiplied by one million (106). It is a term with several variants in meaning, so the meaning should be made clear if this term is used.
Parts per million is related to percent (parts per hundred) as follows:1% = 10,000 ppm or 1/100 = 10,000/1,000,000.
concentration of a solute in grams/10^6 grams solution
1g NaCl/1000g H20 (1,000,000)
0.001 x 1,000,000
1000 ppm is your answer.
In other words, ppm measures the concentration of a chemical in very low quantity. For example, seawater has 0.5 ppm of pure gold, while human blood contains 20 ppm of iron oxide. This unit is used when other units like % and fractions are too big to denote the quantity. Since a percent is one part in a hundred, you can image how small ppm is compared to %.
8 milligrams of Mercury in 100 grams of fish would result in a mercury concentration of 0.8 ppm.
Portable PixmapPPM could also be an abbreviation for Portable Pixmap. This is a common image format used in Unix systems due to the simplicity of the format. The format is as follows:Where width, height, and maxval are in ASCII decimal for the width, height, and maximum sample value of the image, respectively. The header portion can also include human-readable comments by using the # character followed by a comment. The image data is just a bunch of uncompressed bytes containing the red, green, and blue sample values of each pixel. There are similar formats called Portable Greymap (PGM) and Portable Bitmap (PBM), and they are defined and treated similarly.
There are many tools for transforming and converting files of these types to other formats. Search for Netpbm for more information.
ppm = part per million; vpm = volume per million 1 ppm = 1 milligram/kilogram or 1 milligram/liter
Parts per million, equivalent to milligrams per Liter.
parts per million or parts/1000000
Its concept is not much different than percent or parts/100.
it means parts per million.:) ur welcome!
No, the inorganic chemistry is only a chapter of the chemistry.
Organic Chemistry is probably easier, but in inorganic chemistry you will learn more. So academically speaking Inorganic Chemistry
Highly Inorganic, Radioactive and Poisonous
Inorganic chemistry. (A few compounds that DO contain carbon are part of inorganic chemistry too.)

there are five branches: inorganic, organic, analytical, physical, and biochemistry. they could be further broken down into sub-branches such as organometallic chemistry, physical organic chemistry, electroanalytical chemistry, and so on and so forth.

In chemistry, ppm means 'parts per million'

If organic chemistry study the chemistry of carbon compounds the inorganic chemistry stydy the remaining part.
Inorganic chemistry is the chemistry of compounds that don't contain the hydrocarbon radicals.
