Asample of aluminum is placed in a 25-ml graduated cylinder containing 10.0 ml of water. the level of the water rises to 18.0 ml. aluminum has a density of 2.7 g/ml. calculate the mass of the sample.

The mass of the aluminium sample is 21.6 grams.

Explanation:

Mass of the sample of aluminium = m

Volume of the aluminium = V

Density of the aluminum = d = 2.7 g/mL

Initial level of water mark in cylinder = 10.0 mL

Final level of water after sample is immersed = 18.0 mL

Volume occupied by the sample = V = 18.0 mL - 10.0 mL = 8.0 mL

The mass of the aluminium sample is 21.6 grams.

The mass of the aluminum sample placed in the 25-mL graduated cylinder is 22 g.

A graduated cylinder contains 10.0 mL of water and after a piece of aluminum is added the volume increases to 18.0 mL. The volume of the piece of aluminum is equal to the differences in the registered volumes of water.

The piece of aluminum has a volume of 8.0 mL and its density is 2.7 g/mL. The mass of this piece is:

The mass of the aluminum sample placed in the 25-mL graduated cylinder is 22 g.
