The density of a ring that may be silver, platinum, or a white gold alloy is being measured. Its mass under dry conditions is 4.29 g. In water at 20 °C having a density of 0.998 g/cm³, the mass is found to be 4.09 g. Think & Prepare 1. To find the density of an object you need its mass and volume. How can you accurately determine the volume of the ring? 2. How can you use the weightloss of the ring in water to determine the volume of the ring? What is the density of the ring? ✓ g/cm³ For comparison with the final answer (no need to enter an answer for this comparison), density of gold = 19.3 g/cm³ density of platinum = 21.45 g/cm³ density of silver = 10.49 g/cm³ density range of alloy = 14.7 g/cm³ to 16.9 g/cm³
