## In science and engineering, the parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction. Since these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of measurement. Commonly used are parts-per-million (ppm, 10−6), parts-per-billion (ppb, 10−9), parts-per-trillion (ppt, 10−12) and parts-per-quadrillion (ppq, 10−15). This notation is not part of the

Ppm = mass fraction x 106 = 0 We know the mole fractions of CO 2 in the reference gases very accurately. In this case they were 370.50 ppm (W1), 379.93 (W2), and 389.72 (W3). For each of these three we register a voltage, which establishes a relationship between voltage and CO2 mole fraction.

Results show that the change in relative CH4 levels can be determined at rather high accuracy in the 2-700 ppm mole fraction range, with modest efforts of

1 ppm is 0.0001%. If not by molae fraction, by what basis, and what is the other constituent? If it is hydrogen sulphide mixed in another gass, the ppm is most likely expressed as a mole fraction.

## In water solution, the concentration C in parts-per million (ppm) is equal to the concentration C in milligrams per kilogram (mg/kg) and equal to 1000000 times the molar concentration (molarity) c in moles per liter (mol/L), times the solute molar mass in grams per mole (g/mol), divided by the water solution density at temperature of 20ºC 998.2071 in kilograms per cubic meter (kg/m 3):

Ch#10 | Lec#2 | Raoult s Law | Mole fraction, Parts per million, billion, Trillion (ppm, ppb, ppt) #chemistry11 PPM to Molarity Formula: To find the molarity from PPM, first multiply the PPM value with 0.001 and divide the resultant value by atomic weight. Formula: Molarity = ( Parts Per Million (PPM) value × 0.001 ) / Atomic Weight The mole fraction of solute i is written as X i. Parts Per Million (PPM) and Parts per Billion (PPB): "Parts per" is a convenient notation used for low and very low concentrations.
