Question

A 0.317 gram bauxite mineral sample contains aluminum. In the analysis method, the bauxite sample was dissolved. Then, with the addition of aqueous ammonia, Al2O3 x H2O precipitate formed, and the precipitate was filtered and ignited at 1000 Celsius to obtain anhydrous Al2O3 weighing 0.1798g. What is the percent mass of the aluminum in the bauxite mineral sample?

Step 1

To calculate the mass of Al2O3 in the precipitate, we subtract the mass of the crucible from the mass of the crucible with the anhydrous Al2O3. Mass of Al2O3 = Mass of crucible with anhydrous Al2O3 - Mass of crucible Mass of Al2O3 = 0.1798g - 0g Mass of Al2O3 = Show more…
