A piece of an aluminum can was cut into small pieces. Then 0.422 g of the chips from the can was used to

Question

prepare potassium alum according to the procedure we used. Calculate the theoretical yield (in g) of potassium
alum that could be obtained in the reaction. (Alum MW=474.41 g/mol).

Answer 1

Potassium alum is KAl(SO4)2.12H2O
0.422g Al x (molar mass KAl(SO4)2.12H2O/atomic mass Al) = ? theoretical yield.
