To find the volume of the 7 gold rings, we can use the formula for density, which is:
Density = Mass / Volume
We need to rearrange this formula to solve for volume:
Volume = Mass / Density
First, we need to find the total mass of the 7 gold rings:
Total Mass = Number of Rings × Mass of Each Ring
Total Mass = 7 rings × 7.3 grams/ring = 51.1 grams
Now we can use the density of pure gold to find the volume:
Volume = Total Mass / Density
Volume = 51.1 grams / 19.3 g/ml ≈ 2.65 ml
Therefore, the total volume of the 7 gold rings would be approximately 2.65 ml.
