## anonymous one year ago A student used a balance and a measuring cylinder containing water to find the density of a small stone. mass of stone = 20g original volume of water in cylinder = 30 cm^3 volume of stone and water = 38 cm^3 Density of stone = ________

the volume of the stone, is: 38-30=...cm^3

3. anonymous

8 cm^3

4. Michele_Laino

correct!

5. Michele_Laino

so, the requested density, is: $\Large \delta = \frac{m}{V} = \frac{{20}}{8} = ...\frac{{{\text{grams}}}}{{{\text{c}}{{\text{m}}^{\text{3}}}}}$

2.5

7. Michele_Laino

correct!
