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
