"Calculate the experimental mole ratio of iron:complex in flask 1 and flask 2"
(Report mole ratio as a number)

Equation I have is 5Fe^2+ + MnO4^- + 8H^+ ---> 5Fe^3+ + Mn^2+ +4H2O

I don't get how to do this, anyone know?

I used the equation in my lab manual which says:

Experimental Mole Ratio = Calculated number of moles of iron/Number of moles of complex theoretically present

So I plugged in my info and got 16.39 for flask 1 and 15.14 for flask 2

So now what am I supposed to do to show the mole ratio?



There's another Q after that one that's similar


I have to find the experimental mole ratio between oxalate : complex

I found the moles theoretically present in the complex which was 5.34x10^-4 in flask 1 and 5.02x10^-4 in flask 2

In the end I got 2.7 for flask 1 and 2.71 for flask 2... I don't get how to put that in ratios either

Assuming numbers you have calculated are correct, these numbers are the experimental mole ratio, you have to place them in your lab report. Probably listing them with the average value won't hurt.
