In water solution, the concentration C in parts-per million (ppm) is equal to 1000 times the concentration C in grams per kilogram (g/kg) and equal to 1000000 times the concentration C in grams per liter (g/L), divided by the water solution density at temperature of 20ºC 998.2071 in kilograms per cubic meter (kg/m 3) and approximately equal to Water hardness follows these guidelines: 0 - 4 dH, 0 - 70 ppm : very soft 4 - 8 dH, 70 - 140 ppm : soft 8 - 12 dH, 140 - 210 ppm : medium hard 12 - 18 dH, 210 - 320 ppm : fairly hard 18 - 30 dH, 320 - 530 ppm : hard higher : liquid rock (Lake Malawi and Los Angeles, CA) General hardness is the more important of the two in biological processes. 70 ppm Makeup Alkalinity for Desired pH 70 ppm/4 COC 17.5 ppm Required Reduction in Cooling Water Alkalinity 200 -17.5 182 ppm Sulfuric Acid Required per ppm of Alkalinity Reduction 1 ppm of 93% (66 Baume) Acid per ppm Alkalinity reduction 182 ppm x 1 = 182 ppm Pounds /day of Acid Required for Alkalinity Reduction 182 ppm X 7. 7 M ppd (640 GPM Divide the ppm hardness value by 17.1, the conversion factor for ppm to gpg. The result is the water hardness expressed in grains per gallon. For example, say you have a water hardness value of 180 ppm. 03: Prepare 70 ppm from K solution using K,CO, in 1L, 0.4L of distal water? (25 Marks) 04: What is the volume required to prepare 0.2M of HNO, (30%) in 150 ml distill water, if the specific gravity - 1.51 (gm/ml)?

So to convert from ppm to percent, divide the ppm by 10000: x (%) = x (ppm) / 10000 . Example: find how many percent are in 300ppm. x (%) = 300ppm / 10000 = 0.03%. ppm to percent conversion table PPM, or parts-per-million, is a way of expressing very dilute concentrations of substances. Usually describes the concentration of something in water or soil. One ppm is equivalent to 1 milligram of something per liter of water (mg/l) or 1 milligram of something per kilogram soil (mg/kg).

Let the mixture sit for at least one-half hour before drinking. Be sure to obtain the dry granular calcium hypochlorite since once it is made into a liquid solution it will begin to degrade and eventually become useless as a disinfecting agent. A greenhouse gas (sometimes abbreviated GHG) is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor (H 2 O), carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), and ozone (O 3).Without greenhouse gases, the average temperature of Earth's surface would be about Assuming a dissolved oxygen concentration of 70 ppm mgL in a 200 mL water from CHM MISC at Mapúa Institute of Technology This dew-point calculator will give you an equivalent measurement in dew point (ºC or ºF), ppm(v), ppm(w), g/m³ and lb/MMSCF.
