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%
