WebMole Fraction. The mole fraction or molar fraction (xi) is defined as the amount of a constituent (expressed in moles), n i, divided by the total amount of all constituents in a mixture (also expressed in moles), n tot: x i = n i n t o t. The sum of all the mole fractions is equal to 1: ∑ i = 1 N n i = n t o t; ∑ i = 1 N x i = 1. Web11 de set. de 2024 · Normality is the number of equivalent weights, EW, per unit volume. An equivalent weight is the ratio of a chemical species’ formula weight, FW, to the number of its equivalents, n. EW = FW n. The following simple relationship exists between normality, N, and molarity, M, N = n × M. This page titled 16.1: Normality is shared under a CC BY …
