The answer of the the percentage of zinc in the alloy is 33.33%.
Mass percent is the mass of the element or solute divided by the mass of the emulsion or solute. The result is multiplied by 100 to give a percent. The formula for the quantum of an element in a emulsion is mass percent = (mass of element in 1 operative of emulsion / mass of 1 operative of emulsion) *100.
An alloy, metallic substance comprised of two or more elements, as either a compound or a solution. For example: Brass is an alloy of two metals: copper and zinc.
According to question,
Mass of pure Gold = 64g
Mass of pure zinc = 32 g
Now,
Total weight of alloy is = 64 + 32 = 96 gram
32 g of which is zinc
So percentage (%) of zinc in the alloy is 32/96*100 = 33.33 %
Hence, the percentage of zinc in the alloy is 33.33%.
