we were assigned to dilute 900ppm in to 18ppm by using only 250ml vol flask. firstly we did calc and convert 900ppm to 0.9 ppm to dilute in 1 liter. to begin the experiment we took 0,225g of kmno4 and dissolved in to 250 vol flask. then further we took 10 ml sample sol and dissolved in to 100 ml vol flask and put it in to a spectrometer and got value of 0.145A . upon further calc we got v2 as 50ml . need to find DF, % error (expval and accptVal), molarity, molality. please write the whole report. thank you The format, tables, introduction, procedure and observation, result, calculations, discussion and conclusion

Support the tube on a stir plate and over a 15-minute period add, using the 10mL burette, 5mL of a nominal 600mM solution of 2,4 pentandione in methanol under constant stirring. To the resulting solution, add via a 10mL burette 3mL of a nominal 450mM sodium acetate solution stirring constantly. At this point, a red crystalline solid should begin to precipitate. Transfer and support the reaction vessel in the hot water bath and once the reaction mixture has reached a stable temperature in the desired range, maintain the reaction mixture at this temperature, under constant stirring, for a 15-minute period Initial weight of iron(III) chloride hexahydrate: 0.4053g The final weight of the reaction tris(acetylacetonate)iron(III): 19.6 mg 3.
