4.      An archeologist found an old object that weigh 15, 164 grams. They measured the volume of the object by the water displacement experiment and found the volume as 1000 cm3. If the object is made of gold and copper, calculate the volume percentage of the gold and the copper. ( the density of gold is 19.3 g/cm3 and density of copper is 8.96 g/cm3).
