Suppose 1.624g of salt FeSO4 is placed in a 250mL flask to which 50mL of water and 10 mL of 3M H2SO4 are added. How many mL of .1062 M KMnO4 solution are required to reach the endpoint?

Answer 1

first step is to convert all measurements to moles.

Then consult your equation to figure amounts of moles per reagent.

Answer 2

What about the mL of water and H2SO4

Answer 3

water is 0M H2SO4
10mL of 3M contains 0.03 moles H2SO4
