Suppose you have 150. mL of a substance with a density of 42.0 g/dm3 and want to determine the mass of the substance. The calculation can be broken down into three steps. First, convert the volume from milliliters to liters. Then, convert the volume from liters to cubic decimeters. Finally, determine the mass of the sample in grams. Show the unit analysis by placing the correct components into the unit‑factor slots. The question marks (?) represent the answer to the previous step.

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.
