The mass unit associated with density is usually grams. If the volume (in mL or cm) is multiplied by the density (g/mL or g/cm³) the volume units will cancel out, leaving only the mass units. Keep in mind that the volume and density must use the same volume unit for the cancellation. If a large marshmallow has a volume of 2.00 in³ and density of 0.242 g/cm³, how much would it weigh in grams? 1 in3 = 16.39 cm³. Express your answer in grams to three significant figures. • View Available Hint(s) ν ΑΣφ ? mass of marshmallow = g

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.
