    Answer:

    % yield = 200%

    Explanation:

    By using 145 gram of aluminium

    Using 26.982 g/mol of Al, 101.96 g/mol of Aluminium oxide is produced

    Using 145 grams of aluminium, the yield of Aluminium oxide  would have been = (101.96 g/mol/26.982 g/mol)/145 grams

    = 547.9282485 gram

    Now % yield = actual yield /theoretical yield * 100

    Substituting the given values, we get –

    % yield = (547.928/270) *100

    % yield = 200%
