      Maximum ozone concentration in water varies directly by concentration of the gas in air and inversely by temperature: for example 1.5% feed gas (by weight) will have a maximum concentration of about 11 ppm (mg/L) in water at 5 degrees C and 6.4 ppm at 20 degrees C. Doubling the concentrations of ozone in the feed gas will double the ...

      Since the stock standard is expressed in mg/mL and the working standard is expressed in mg/dL, we must first convert the concentration of them both to the same units. Stock standard = 10 mg/mL x 100 mL/1dL = 1,000 mg/dL. 2. To determine the dilution that must be made to yield a working standard of the desired concentration, we use the following ...

      Convert percent transmittance into a decimal (example: 90% = 0.9). Record on data table above. Find the reciprocal of the decimal form and record that as 1/T on the data table above. What are you going to Graph? Make a graph of 1/T vs. molar concentration. Make a linear fit (If done correctly, this should be a straight line graph)

      For the LST program staff used a dispersion model (ISCST3) to convert the 2.5 μg/m3 concentration into mass daily PM10 emissions numbers based on the size of the project, location of the project, and distance to the sensitive receptor. The results were then incorporated into an LST look-up table.

      What is its concentration in ppm? Convert the mass in grams to a mass in milligrams: 1.25g = 1.25 x 1000mg = 1250mg . Re-write the concentration in mg/L = 1250mg/L = 1250ppm . 2. A solution has a concentration of 0.5mg/mL. What is its concentration in ppm? Convert the volume to litres: volume = 1mL = 1mL ÷ 1000mL/L = 0.001L
