Bookmark In this experiment, a stock solution of acetylsalicylic acid will be prepared by dissolving 0.450g of pure acetylsalicylic acid in NaOH solution and enough water to make 250.0ml of solution. Calculate the concentration of this solution. You will dilute the stock solution you prepare using iron (III) chloride solution to make the following dilution of the iron( lll) salicylate complex. how do i calculate for the concentraion of Fe3+ x SA? PLease show me ONE calculation for dilution #2 dilution Volume (ml) stock solution Volume(ml) dilute solution (mol/L) dilute solution blank Blank Blank Blank #1 1.00 100.0 0 #2 3.00 100.0 ? #3 5.00 100.0 ? #4 7.00 100.0 ?

Explanation / Answer

molecular weight of acetylsalicylic acid is = 180.16 g/mol

180.16 g in 1L will give 1M solution

therefore .450 g in 250 ml will give you, 0.450g/180.16g/mol/.4L = 0.0062 M

the remaining part of the question is not clear
