Adding aqueous silver(I) nitrate to aqueous gallium(III) bromide results in the precipitation of silver(I) bromide. A sample of gallium(III) bromide weighing 0.165 g was dissolved in water and treated with silver(I) nitrate, resulting in the precipitation of 0.299 g of silver(I) bromide. Calculate the quantity of the reacted gallium present in the sample of gallium(III) bromide, as a percentage of the total mass.
