The concentrated solution is 1:800.
Then it is diluted 1:20 before use.
So amount of the concentrated solution in 250 ml of diluted solution = 250/20 = 12.5 ml
Amount of KMnO4 in 800 ml of the concentrated solution = 1 ml
Amount in 12.5 ml = 12.5/800
Total amount of KMnO4 = 12.5/800 * 4 * 28 = 1.75 ml

A standard solution of iron was made by weighing 0.075 g of Fe(NH4)2(SO4)2 6(H2O) in 250 mL. Aliquots of this standard solution (see below) were transferred to a 100 mL volumetric flask, pH adjusted with citrate, and reacted with hydroquinone and o-phenanthroline and diluted to volume (100 mL). The absorbance was measured in a 1.0-cm cell using a Genesys 20 Spectrophotometer at 508 nm: Aliquot of standard solution Absorbance 1.0 mL 0.079 2.0 mL 0.163 5.0 mL 0.413 10.0 mL...
