As World War I came to an end, Russia gained control of Armenia, and fortunately for Armenia, the country was spared from much of the destruction and devastation of World War II in the 1940s.istorically Armenia and Azerbaijan have been long associated with Asia and the Middle East. In recent years some sources now consider them to be more closely aligned with Europe based on their modern economic and political trends. I.E.
mr. green thumb 01 New Member. just measured the ppm of rain water and it is 3-5 which is the same as reverse osmosis. Most tap water is 200-350 ppm which is not good for growing. So if you want good water cheap...catch is outta your gutters. plants will love it! Oct 16, 2010. #1.
The unit â1 ppmâ can be used for a mass fraction if a water-borne pollutant is present at one-millionth of a gram per gram of sample solution. When working with aqueous solutions, it is common to assume that the density of water is 1.00 g/mL. Therefore, it is common to equate 1 gram of water with 1 mL of water.Consequently, ppm corresponds to 1 mg/L and ppb corresponds to 1 Î¼g/L. One part per trillion (ppt) denotes one part per 1,000,000,000,000 parts, one part in 10 12, and a value of 1 Ã 10 â12. 2  This is equivalent to one drop of water diluted into 400 Olympic-size swimming pools (2,500 m 3), or about three seconds out of every hundred thousand years.
