25g of a sample of ferrous sulphate was dissolved in water containing dilute h2s04 and the volume made up to one litre. 25ml of this solution required 20ml of N/10 kmn04 solution for complete oxidation. Calculate the percentage of f2s047h20 in the sample The right answer 88.96%
0.02 x 0.1 = 0.002
0.002 x 1000ml x 293g/mol / 25ml = 23.44
23.44 / 25g x 100% = 93.76%
