Normality equation n1v1 n2v2
Weby Henry’s Law determines solubility of gas in a liquid. y When two non-reacting solutions of different normalities are mixed, the normality of final solution can be calculated by using following equation. N1V1 + N2V2 = N3(V1 + V2) y Human RBC is isotonic with 0.91% NaCl y Osmotic pressure is best colligative property to determine molecular ... Web11 de abr. de 2024 · Sarah diluted it up to the mark to make the final volume V 2 = 100 mL. So we can easily apply the normality equation and find the final concentration, i.e., N2. ∴ N1V1 = N2V2. ⇒ (0.05) (25) = N 2 (100) ∴ N 2 = 0.0125 N. Result: Sarah diluted the HCl …
