the aluminum (FW= 26.98 g/mol) in a 1.200 g sample of impure ammonium aluminum sulfate was precipitated with aqueous ammonia as the hydrous Al2O3.xH2O. the precipitate was filterd and ignited at 1000 degrees C to give anhydrous Al2O3 (FW = 101.96 g/mol) which weighed 0.1798 g. calculate the percentage of aluminium in the sample
