Answer:
density of ring is = 21.4 g/cm³
Explanation:
From the formula;
Density = Mass/Volume
Plugging in the relevant values, we have;
Density = 107g/5mL
Density = 21.4 g/mL
We need to convert this density to a more standard form of g/cm³.
From conversions;
1 g/mL = 1 g/cm³
Thus; density of ring = 21.4 g/cm³
