Diagram 1 illustrates a measuring cylinder with water inside. Diagram 2 shows that same measuring cylinder and water after $10$ identical solid glass spheres have been placed in it. Each sphere has a mass of $10\,\text{g}$. What is the density of the glass used to make the spheres?
- A$0.25\,\text{g cm}^{-3}$
- B$0.40\,\text{g cm}^{-3}$
- C$2.5\,\text{g cm}^{-3}$
- D$4.0\,\text{g cm}^{-3}$
