A 0.7875 -g portion of manganese dioxide (MnO2, MW 86.94 g/mol) was added to an acidic solution in which 1.1402 - g of a chloride containing sample was dissolved. Evolution of chlorine gas took place as a consequence of the following reaction: MnO2 (s) + 2 CI¯ + 4H+ Mn2+ + Cl2 (g) + 2 H₂O After the reaction was complete, the excess MnO2 was collected by filtration, washed, and weighed and 0.1539 - g was recovered. Express the results of this analyssi in terms of percent aluminium chloride (AICI3, MW = 133.34 g/mol).
