\( 32 \mathrm{~g} \) of a sample of \( \mathrm{FeSO}_{4} \cdot 7 \mathrm{H}_{2} \mathrm{O} \) were dissolved in dilute sulphuric acid and water and it's volume was made up to 1 litre, \( 25 \mathrm{~mL} \) of this solution required \( 20 \mathrm{~mL} \) of \( 0.02 \mathrm{MKMO}_{4} \) solution for complete oxidation. Calculate the weight \( \% \) of \( \mathrm{FeSO}_{4} \cdot 7 \mathrm{H}_{2} \mathrm{O} \) in the sample.https://bit.ly/YTAI_PWAP https://www.pw.live
