# An irregularly shaped stone was lowered into a graduated cylinder holding a of volume of water equal to 2 mL. The height of the water rose to 7 mL. If the mass of the stone was 25 g, what was its density?

Density: $5$ grams per cubic centimeter

#### Explanation:

Note: $1 \text{ ml" = 1 " cc}$

If the water rose $7 \text{ ml" - 2" ml"=5" ml}$
then the stone had a volume of $5 \text{ ml" or 5 " cc}$

With a mass of $25 \text{ g}$
it must have a density of
color(white)("XXX")(25" g")/(5" cc") = 5 " g/cc"
