🤓 Based on our data, we think this question is relevant for Professor Browning, Wilson & De Backere's class at TORONTO.
We have to determine if the found bracelet if made of silver or not.
We have the density of silver metal, 10.5 g/cm3. We will calculate the density of the bracelet and compare it with the density of silver to determine if the bracelet is made from silver metal.
The formula for density is:
You are beachcombing on summer vacation and find a silver bracelet. You take it to the jeweler and he tells you that it is silver plated and will give you $10 for it. You do not want to be swindled so you take the bracelet to your chemistry lab and find its mass on a balance (80.0 g). To measure the volume you place the bracelet in a graduated cylinder, containing 10.0 mL of water at 20 oC. The final volume in the graduated cylinder after the bracelet has been added is 17.61 mL. The density of silver at 20 oC is 10.5 g/cm3 and 1 cm3= 1 mL.
What can you conclude about the identity of the metal in the bracelet?
