Calculations: Calculate the number of moles of oxalate present in each sample. Then assuming a 100. gram sample of the coordination compound, determine the moles of oxalate ion that is present. The data for the three determinations of moles of oxalate/100 g of sample should be within 1%. An appropriate data table for this experiment is Molarity of KMnO4 (M) Mass of compound analyzed in titration 1 (g) Mass of compound analyzed in titration 2 (g) Mass of compound analyzed in titration 3 (g) Volume of KMnO4 used in titration 1 (L) Volume of KMnO, used in titration 2 (L) Volume of KMnO4 used in titration 3 (L) Moles of KMnO4 used in titration 1 (moles) Moles of KMnO, used in titration 2 (moles) Moles of KMnO, used in titration 3 (moles) Moles of oxalate in titration 1 (moles) Moles of oxalate in titration 2 (moles) Moles of oxalate in titration 3 (moles) Moles of oxalate/100 g in titration 1 Moles of oxalate/100 g in titration 2 Moles of oxalate/100 g in titration 3 Average moles of oxalate per 100 g % difference between the largest and smallest values of moles of oxalate per 100 g
