Answer:

The density of the ring. which has a mass 7.21g and a volume of 0.65cm³ is

11.09g/cm³

Step-by-step explanation:

This problem bothers on the density of substances

Given data

Mass of ring =7.21g

Volume of ring =0.65cm³

Density ρ =?

We know that the density =

mass/volume

ρ= 7.21/0.65

ρ= 11.09g/cm³
