Question

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 = ________

Answer 1

Answer 2

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

Answer 3

8 cm^3

Answer 4

correct!

Answer 5

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

Answer 6

2.5

Answer 7

correct!

Answer 8

thats the ans?

Answer 9

Answer 10

yes!
density= 2.5 grams/cm^3
