Determine the aluminum present in 2.402 g of an impure sample of chlorides with aluminum chloride treated with ammonia precipitated as Al2O3. xH2O hydrated. The precipitate was filtered and calcined at 1000 °C to form anhydrous Al2O3, whose weight was 0.3076 g. Calculate the percentage of aluminum in the sample? MW (AI) =26.9815 g/mol MW (Al2O3) = 101.96 g/mol a. 10.17 % Al b. 16.94% Al c. 1.63% Al d. 6.78% Aluminum e. 3.4% Aluminum
MW (AI) =26.9815 g/mol
MW (Al2O3) = 101.96 g/mol
a. 10.17 % Al
b. 16.94% Al
c. 1.63% Al
d. 6.78% Aluminum
e. 3.4% Aluminum
