No 100 ppm of NaCl = 100 mg NaCl/1 L = 67,87 ppm (67,87 mg/L) of Na
ppm by volume is "parts per million" by volume as opposed to ppm by weight. ppm by volume and ppm by weight are not the same thing It has been suggested that the drinking water in West Hampshire be adultery with 1 ppm by volume of fluoride. This is an example of ppm by volume
Answer It stands for principle and practices of management, which gives detail study about the working of an organization.Answer It could also stand for "parts per million", which is a unit for measurement of concentration.
50ppm is better.
1 mole =how much ppm
200 ppm
Sodium hypochlorite has two main properties... biocidal and oxidative. under 150 ppm it can be a GREAT sanitizer. over that it will start to oxidize certain surfaces.
The proper way to apply hand sanitizer is to first make sure your hands are visibly clean. Then, apply a small amount of sanitizer, about the size of a coin, to the palm of one hand. Rub your hands together, making sure to cover all surfaces, including the back of your hands, between your fingers, and under your nails, until the sanitizer is dry.
Thus it is not yet possible to derive proper motions with PPM quality for all AC stars.

Residential pools: 1.0 - 3.0 ppm; Commercial pools: 3.0 ppm - 5.0 ppm; Bromine levels: 4.0 - 6.0 ppm
Technically, since it's a hand sanitizer and sanitizer means "to make sanitary, as by cleaning or disinfecting" then obviously it's the dirt get cleaned and not the sanitizer get dirty.

Carbon dioxide levels are not decreasing in the atmosphere, in fact, they are increasing. In 1960 levels were 316 ppm. In 1970 levels were 325 ppm. In 1980 levels were 338 ppm. In 1990 levels were 353 ppm. In 2000 levels were 369 ppm. In 2010 levels were 388 ppm. Jan of 2012 levels were 393.09 ppm. As of today we are at 393.68 ppm at Manua Loa.
46 ppm is 0.0046%
