To find the density of an object, you can use the formula:
\[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \]
In this case, the mass of the silver bracelet is 18 grams, and the volume is 2 cubic centimeters. Plugging these values into the formula, we get:
\[ \text{Density} = \frac{18 , \text{grams}}{2 , \text{cubic centimeters}} = 9 , \text{grams per cubic centimeter} \]
Therefore, the density of the silver bracelet is 9 grams per cubic centimeter.
