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

It measures the mass of the chemical substance or concentration per unit weight of water/solid or volume of one part of gas. One part per million is equal to 0.000001 units. 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.

$Ppm mole fraction$

PPM is short for parts per million, which is exactly as it sounds. It’s a faction per million units of some number or value. For instance, if you have .00005 atoms of oxygen per cubic meter of air, that means that in 1 million cubic meters you have 50 atoms per million units. How to calculate PPM Mole fraction is useful when two reactive components are mixed together, as the ratio of the two components is known if the mole fraction of each is known. Multiplying mole fraction by 100 gives mole percent, which describes the same thing as mole fraction, just in a different form. Units of volume fraction or mole fraction are frequently used for gas concentrations. The most common volume fraction units are ppm (ppm by volume) which is defined as Note that here, again, the factor is really a conversion factor, with units of volume fraction).
