Suppose you have two 100-mLmL graduated cylinders. In each cylinder, there is 44.0 mLmL of water. You also have two cubes: one is lead, and the other is aluminum. The density of lead and aluminum are 11.3 g/mLg/mL and 2.70 g/mLg/mL respectively. Each cube measures 3.0 cmcm on each side. After you carefully lower each cube into the water of its own cylinder, what will the new water level be in each of the cylinders? Express your answer to three significant figures and include the appropriate units.

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
