WebSolution: 1) Preliminary calculations: mass of acetone: (3.30 mL) (0.789 g/mL) = 2.6037 g. moles of acetone: 2.6037 g / 58.0794 g/mol = 0.04483 mol --- need to look up formula of … 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 …
