An irregularly shaped stone was lowered into a graduated cylinder holding a volume of water equal to 2.0 mL. The height of the water rose to 7.0 mL. If the mass of the stone was 25 g, what was its density?

Density = 5 g/mL

Explanation:

Given data:

Volume of water = 2.0 mL

Volume of water + stone = 7.0 mL

Mass of stone = 25 g

Density of stone = ?

Solution:

Volume of stone = (volume of water + stone) - volume of water

Volume of stone = 7.0 mL - 2.0 mL

Volume of stone = 5.0 mL

Density of stone = mass/ volume

Density = 25 g/ 5.0 mL

Density = 5 g/mL
