An alloy of aluminum and magnesium was treated with sodium hydroxide solution, in which only aluminum reacts. If a sample of alloy weighing 1.118g gave 0.1068 g of hydrogen, what is the percentage of aluminum in the alloy? The unbalanced equation for the reaction is: Al(s) + NaOH + H2O NaAl(OH)4 + H2
