How to solve this titration problem?
« on: March 07, 2010, 01:16:53 AM »
four iron tablets which had a mass of 1.25g was dissolved in 50cm3 of 1.0 mol dm-3 of H2SO4. and then diluted to have a volume of 250cm3 with distilled water.

7.3 of 0.01 mol dm-3 KMnO4 was required to neutralise 25cm3 of the solution.

What is the mass of iron in the tablet?

Literature value, each tablet contains 300mg of FeSO4

PLEASE HELP I AM STUCK

As usual - start with the reaction equation.
