Water having dissolved mineral hardness of 1 GPG (grain per gallon) or more qualifies it as Hard water according to the Water Quality Association of the United States definition. If you multiply GPG rating by 1.7 you will get the PPM.

Show how to calculate the molar concentration of arsenic in a water sample that has 1 ppm arsenic As?
1 ppm means one gram of arsenic per 1,000,000 grams of water 1,000,000 grams of water is 1,000 litres = 1,000 dm^3 (one gram = one ml) assuming we have this quantity of solution: moles arsenic = mass/Mr = 1/74.9 = 0.0133511348 moles but this is for 1,000 dm^3, so for 1 dm^3 we have 1000th of this amount, which is 1.335113485 x 10^-5 moles So the molar concentration is 1.34 x 10^-5 mol.dm^-3 (I hope)
What is conductivity and pH value of dm water?
ph of DM water is 6.5 to 7.1 conductivity of Dm water is near 000
Which does not cause hardness of water?
Magnesium sulfate (MgSo4) does not cause hardness of water.
What is a good level of ppm in well water?
"ppm" simply means 'parts per million' and describes the quantity of any substance in water. For example -Iron should be less than 3 ppm."ppm" simply means 'parts per million' and describes the quantity of any substance in water. For example -Iron should be less than 3 ppm.
How to convert 10 ppm mole of H2O to ppm wt in natural gas?
10 ppm mole multiply by molecular weight of water then divided by sample density
What is permissible value for hardness in well water for drinking purpose?
60 -100 ppm is the currently acceptable hardness level for drinking water in US and Canada.60 -100 ppm is the currently acceptable hardness level for drinking water.
How do you Calculate the total hardness of water sample that contains ppm magnesium and ppm calcium?
Answer will be (mg/L) as CaCO3 units of ppm are the same as mg/L. Hardness = 2.5(mg Ca/L) + 4.1(mg Mg/L) In this case: 2.5x78.4 + 4.1x104.5 = 624.45 mg/L
How do you find what the ppm is of a 24-foot round pool?
There are ppm's to chlorine, pH, alkalinity, water hardness, copper etc., etc, etc, etc. Rethink and ask in a different format.
What is the definition of dm water?
Demineralised water. DM water is demineralised water . Dissolved impurities and dissolved gases in water. Some times water is hard, temperary hardness or permanent hardness and which is badly affects the boiler which helps formation of scales in sides the boiler. In the process of purification of water Coagulation, sedimentation, filteration are the first stages. After filteration water allowed to enter into Activated carbon filter for absorbing dissolved carbondioxide. For removing temporary hardness and permanent hardness ion exchanging process used. By Ion - exchange process from which the minerals have been removed and get Demineralized water.

How hard is hard water?
It all depends on how fast you are going when you hit it.=============================================Water hardness varies from area to area. Hard water is water that has high mineral content (in contrast with soft water). Hard water minerals primarily consist of calcium (Ca2+), and magnesium (Mg2+) metal cations, and sometimes other dissolved compounds such as bicarbonates and sulfates.Because it is the precise mixture of minerals dissolved in the water, together with the water's pH and temperature, that determines the behaviour of the hardness, a single-number scale does not adequately describe hardness. Descriptions of hardness correspond roughly with ranges of mineral concentrations:Very soft: 0-70 ppm, 0-4 dGH (degrees of General Hardness)Soft: 70-140 ppm, 4-8 dGHSlightly hard: 140-210 ppm, 8-12 dGHModerately hard: 210-320 ppm, 12-18 dGHHard: 320-530 ppm, 18-30 dGHVery hard >530 ppm, >30 dGHAccording to the British Drinking Water Inspectorate shows that drinking water in England is generally considered to be 'very hard', with most areas of England, particularly east of a line between the Severn and Tees estuaries, exhibiting above 200 ppm for the calcium carbonate equivalent. Wales, Devon, Cornwall and parts of North-West England are softer water areas, and range from 0 to 200 ppm.More than 85% of American homes have hard water. The softest waters occur in parts of the New England, South Atlantic-Gulf, Pacific Northwest, and Hawaii regions. Moderately hard waters are common in many of the rivers of the Tennessee Great Lakes, Pacific Northwest and Alaska regions. Hard and very hard waters are found in some of the streams in most of the regions throughout the country. Hardest waters (greater than 1,000 ppm) are in streams in Texas, New Mexico, Kansas, Arizona, and southern California.Source: DWI, Wikipedia,See link below for more information
