The mass fraction of component A in a mixture is defined as: (2.24)mass fraction A=mass of Atotal mass Mass percent is mass fraction×100; mass fraction and mass percent are also called weight fraction and weight percent, respectively. Another common expression for composition is weight-for-...

Several characteristics of chitosan are fundamental in describing the particular molar batch and predicting its chemical and physical properties: the average molar mass of the sample, its average degree of acetylation (DA, given as a percentage) or the fraction of acetylation ([F.sub.A], given ...
The lowercase Greek letter χ (chi) rather than a Roman x are the notations of mole fraction. For mixtures of gases, IUPAC recommends the letter y. It is a method of expressing the composition of a mix with a dimensionless quantity, the mass fraction (percentage by weight, wt%) and ...
w = a vector containing the composition in mass fraction. Must sum to 1 elem = cell array of elements in the same order as they are listed in w Ouput: x = composition vector in mole fraction Example w = [0.01, 0.1, 0.89];
