You have two objects made of the same substance. Object 1 is a cube with a mass of 180.1 g. You measure the side of the cube using a ruler and find it to be 3.17 cm. Object 2 is a sphere with a mass of 90.1 g. You find the volume of the sphere using water displacement. The volume of the water in a graduated cylinder initially is 120.0 mL, and when the sphere is added the new volume is 135.8 mL. Having found a density of 5.65 g/cm³ for the cube and a density of 5.70 g/mL for the sphere, which one of the following statements is true?   A) The density of the cube appears to be smaller than the sphere because the units used for the two density values are not the same. B) The density of the sphere and cube are not the same because their volumes and masses are different. C) The density of the sphere and cube are different because the shapes of the substance are different D) The density of the cube and sphere should be the same since they are made

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.
