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 …
WebUses of Normality. Normality is used mostly in three common situations. In determining the concentrations in acid-base chemistry. For instance, normality is used to indicate … WebExample - 16. Show that four normals ( real or imaginary) can be drawn from any point P to a given hyperbola, say x2 a2 − y2 b2 = 1. x 2 a 2 − y 2 b 2 = 1. In addition, show that the sum of the eccentric angles of the feet of these four normals is an odd multiple of π. π.
