calculate the number of g fes04 that will be oxidized by 24ml of a 250N Kmn04 in a solution acidified with sulfuric acid. The unbalanced equation for the reaction.
The answer 0.912g
mL x N = # milliequivalents KMnO4.
# m.e. KMnO4 = # m.e. FeSO4
# m.e. FeSO4 x equivalent weight FeSO4 = g FeSO4.
All of that can be put together to make one nice equation.
mL x N x m.e.w. = grams.
24 x 0.250 x 0.152 = 0.0912g FeSO4.
