Question

Which is the best way to determine if an object is made of pure silver?

O Determine the solubility of the object.
O Test to see if the object is chemically reactive.
Determine the density of the object and compare the known density of pure silver.
O Compare the mass of the silver object to the mass of a piece of pure silver.

Answer 1

The correct option is;

Determine the density of the object and compare the known density of pure Silver

Step-by-step explanation:

The density of the object is found by finding the weight of the object, and then finding the volume (of water) the object displaces when it is immersed (in water)

The density is then fond by dividing the weighed mass by the volume the object displaces when immersed

Compare the result of the measured density with that of pure silver. If the two have density, as well as other similar physical characteristics, then the object is likely to be pure silver.
