To calculate the density of the gold ring, you can use the formula:
\[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \]
Given:
- Mass = 15.83 grams
- Volume = 0.82 milliliters
Now, plug these values into the formula:
\[ \text{Density} = \frac{15.83 , \text{grams}}{0.82 , \text{milliliters}} \approx 19.29 , \text{grams/milliliter} \]
Therefore, the density of the gold ring is approximately 19.29 grams/milliliter.
