WebApr 14, 2024 · A six-replication study was conducted to determine estragole linearity in the range of 0.20–20.00 ng/mL. According to the standard addition method, the accuracy of the estragole method was estimated as percent of recovery (% recovery). Each estragole concentration was estimated based on the % recovery. 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. WebThe calculator uses the formula M 1 V 1 = M 2 V 2 where "1" represents the concentrated conditions (i.e., stock solution molarity and volume) and "2" represents the diluted conditions (i.e., desired volume and molarity). To prepare a solution of specific molarity based on mass, please use the Mass Molarity Calculator. twingo cabrio leasing
