A 0.784-g sample of an alloy containing Al and Mg is dissolved and treated to prevent interferences by the alloy’s other constituents. Aluminum and magnesium are precipitated, providing a mixed precipitate of Al(C9H6NO)3 and Mg(C9H6NO)2 that weighs 8.215 g. Igniting the precipitate converts it to a mixture of Al2O3 and MgO that weighs 0.932 g. Calculate the %w/w Al and %w/w Mg in the alloy.
