The relative densities of zinc, brass, copper, gold and silver are respectively 7.1, 8.5, 8.9, 19.3, 10.5. A metal ornament which weighs 0.425kg and can displace 50 x 10^-6m³ of water is made of
Correct Answer: Option B
Density of the metal ornament = Mass of the metal ornament/Volume of the water displaced
D = 0.425/(50 × 10^-6)
D = 8500Kg/m³
R.D = density of object/density of water
R.D = 8.5
