A 6.80-g sample containing only Mn2(SO4)3 and Al2(SO4)3 are dissolved aqueous solution. The metal ions are precipitated, which are pyrolyzed in air to produce 2.39 g of a mixture of Mn2O3 and Al2O3
What was the percent Mn in the original sample?
What was the percent Al in the original sample?
What was the percent Mn in the original sample?
