Calculate the concentration of NaCl in parts per million (ppm). It's essentially like a percentage, which you could analogously refer to as "parts per hundred," but PPM is better suited to substances in much smaller concentrations. 1 ft. water = 0 . 150 mL of an aqueous sodium chloride solution contains 0.0045 g NaCl. The density of water is 1 gm/cm^3, or about 8.34 lbs/gal. Because of the explosive nature of pure hydrazine, it is available for industrial use in 35% active solutions. How much fertilizer should be put in the solution tank? The 150 = the recommended ppm for the crop; the 100 = the injection ratio; the 20 = the % of active ingredient; the 75 is a constant conversion factor used for finding ppm (1 ounce of any 100 percent soluble fertilizer or chemical in 100 gallons of water always equals 75 ppm). It's used to avoid very small numbers. 13 oz. The best way to determine fertilizer needs is to have the soil or foliage tested. If the concentration of #"SO"_2# in air is #"0.5 ppm"#, what is the percent by mass? What is the concentration of #"Cl"^(–)# ions in the diluted solution in ppm? 1.3 oz.
