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.

Solutions and Units of Concentration May 21, 2015 REVIEW: Units of Concentration A Mole Fraction. In chemistry, the mole fraction, x i, is defined as the amount of moles of a constituent, n i, divided by the total amount of moles of all constituents in a mixture, n tot: [latex]x_{i}=\frac{n_{i}}{n_{tot}}[/latex] Mole fractions are dimensionless, and the sum of all mole fractions in a given mixture is always equal to 1.

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. 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.

3.2k views. asked Mar 13, 2018 in Class XII Chemistry by rahul152 (-2,838 points) Mole fraction is a unit of concentration, defined to be equal to the number of moles of a component divided by the total number of moles of a solution. Because it is a ratio, mole fraction is a unitless expression. The mole fraction of all compone ppm to percent converter How to convert percent to ppm.
