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. Parts per million can mean "per mass", "per volume", etc., etc. I'll assume you mean ppm (m) - per mass. In order to find the mole % of the H2S content you have to know the total number of moles in the crude oil.

Ppm mole basis

It is a unit used to express the dilute concentrations of substances in water or soil. human blood. Calculate concentration in ppm For every 1,000 g total solution, have 1 g solute 10 6 total mass of solution mass of component in solution ppm = × 10 grams of blood grams of glucose ppm = × 6 10 1000 ppm glucose 1000 1.0 ppm = × 6 = MW = molecular weight of emission, pounds/mole = 46 for NO2 = 28 for CO = 44 for CO2 MV = volume of one pound mole of gas, SCF/mole = 379 1000000 = converts ppm to cu. ft. of emission Convert emission rate in ppm at one oxygen level in products of combustion to another oxygen level ppmx = ppmm * (20.99 - x) / (20.99 - y) where 2011-04-05 · To convert from ppm by volume to ppm by mass, multiply by the density of the particles. For mineral grains (clay, silt and sand sizes), this will typically be 2.65 g/cm3.

One mole is equivalent to the molecular or atomic mass of the solute. Parts per million, of course, refers to the number of molecules of solute per million parts of a solution. Since both of these units of measurement are 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 solution density ρ in kilograms per cubic meter (kg/m 3): mole.

For mineral grains (clay, silt and sand sizes), this will typically be 2.65 g/cm3. For example, a sample with a volume concentration of 25 µl/l will have a mass concentration of 25*2.65 = 66 mg/l. To calculate %LEL to ppm example Methane 100%LEL = 5%VOL = 50,000 ppm To calculate 50% LEL divide ppm of 100%VOL(50000 ppm) by 2 or multiply by .50 To calculate 10% LEL divide ppm by 10 or multiply by .10 PPM Defintion. PPM is short for parts per million, which is exactly as it sounds.

Consider a 0.300 M solution of NaOH? Calculate the molality of NaOH. PPB stands for "parts per billion" and it is used to measure the concentration of the solution(mole fraction or mass fraction).

You can perform a PPM conversion easily provided you have two quantities in the same unit (or that you can convert into the same unit) or a percentage value. PPM means "parts per million," so to calculate it you divide the amount of the solute by the total amount of solution, them multiply by 10^6. Se hela listan på lenntech.com 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 Basically, ppm is already micromoles per mole.
