A 0.6447-g portion of manganese dioxide was added to an acidic solution in which 1.1402g of a chloride containing sample was dissolved. Evolution of chlorine took place by the following reaction occurs:
MnO2 + 2Cl- +4H+ > Mn+2 + Cl2 + 2H2O

After the reaction is complete, the excess MnO2 is collected by filtration, washed, allowed to dry, and is then weighed; 0.3521g are recovered. Express the results of this analysis in terms of percent aluminum chloride. Assume reaction proceeds completely to the right.
