Question

PLEASE FILL IN THE MISSING CALCULATIONS

Enter mass (/g) of ammonium iron sulphate and the corresponding number of moles:

15.03g

3.83x10-2 mol

Enter the mass of the product obtained/g:

9.42

Enter the mass of the product sample weighed for analysis/g:

0.50

Enter the molarity of the permanganate solution used/M:

0.02

Enter the titre (/ml) of permanganate delivered, and the corresponding number of moles:

56.1

*1.12x10-3 mol

From this, calculate how many moles of oxalate reacted with this amount of permanganate:

Hence, enter the moles of the overall complex weighed out in the sample:

Enter the RMM of the complex

15.03g

3.83x10-2 mol
