Fe2+ A 0.1283 g sample of M3Fe(C2O4)3 was dissolved in dilute acid, and all of the iron was converted to ions. This acidic solution required 20.55 mL of 0.02000 M KMnO4 solution to reach the end point of this titration, in which the products were Fe³+ (aq), Mn²+ (aq) and CO2 (g). (a) Calculate the molar mass of M3Fe(C204)3. (b) What fraction of the total KMnO4 solution was used in the titration of the oxalate ions (C2O4²-) in the titration in part (a)?

Hi I need help finding the rate of disappearance and rate of appearance of NO2 for time's 200 and 300 seconds. I have pasted a screenschot of my excel data table, I just need help figuring out how to get the rate of dissapearance and appearance for NO2. Thank you so much. 1 2 3 890626695 10 11 12 13 14 15 16 17 18 19 A B C D 0 0.0062 0.0116 0.016 0.0198 0.0228 0.0256 0.0278 E F G [NO₂] Times (s) [N205] (A In[N205] 1/[N205] Rate of Di Rate of Appear 0 0.02 -3.91202 00050 100 0.0169 -4.08044 0.0142 -4.25451 200 300 400 500 H 00059 00070 0.012 -4.42285 00083 0.0101 -4.59522 00099 0.0086 -4.75599 00116 600 0.0072 -4.93367 00139 700 0.0061 -5.09947 00164 K
