WebSep 25, 2024 · The normality of a solution is the gram equivalent weight of a solute per liter of solution. It may also be called the equivalent concentration. It is indicated using the symbol N, eq/L, or meq/L (= 0.001 N) for units of concentration. For example, the concentration of a hydrochloric acid solution might be expressed as 0.1 N HCl. WebSo for the equilibrium concentration of Br2, it's 0.60 minus x, so that's 0.60 minus 0.34, which is equal to 0.26 molar. So 0.26 molar is the equilibrium concentration for bromine. For chlorine, it would be the same calculation, 0.60 minus x would be 0.60 minus 0.34, so the equilibrium concentration of chlorine is also 0.26 molar.
