You discover a piece of jewelry that you think might be made of silver. You place the item on a balance and determine that it ha
Amanda [17]

No, this item is not made of pure silver because if it has been made from pure silver that it would have displaced only 1.16cm³ of water but due to the addition of some other low-density element it displaces 1.9cm³ of water.

<u>For pure silver</u>

density of pure silver is = 10.49 g/cm³

mass of silver = 12.2 gram

since, density = mass/volume

          volume = mass/density

                        = 12.2/10.49 cm³

                         = 1.16 cm³

But the actual displaced water is <u>1.9cm³</u>, which means some other element of lower density has been added.

Therefore, it is clear that the given jewelry is not made of pure silver.
