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).

In the video, the water level was 15 milliliters before adding the chain, and 20 milliliters after adding the chain. When I weighed the chain, its mass was 77.3 grams. I believe the chain is solid metal (not gold plated), but is probably a blend of gold and other metals. I looked up that gold has a density of 19.3 g/ml, while the other metals like silver and copper usually blended with gold have a combined density of about 9.7...
