Final answer:
The volume of an object with a mass of 45 g and a density of 3.0 g/cm³ is calculated by dividing the mass by the density, resulting in a volume of 15 cm³.
Step-by-step explanation:
The volume of an object is determined by dividing its mass by its density, as expressed in the formula Volume = Mass ÷ Density. In the given scenario, where the mass is 45 grams and the density is 3.0 grams per cubic centimeter (g/cm³), the calculation yields a volume of 15 cubic centimeters (cm³). This means that within the specified mass and density, the object occupies a space of 15 cubic centimeters.
Volume = Mass ÷ Density
Given that the mass of the object is 45 g and the density is 3.0 g/cm³, we can calculate the volume as follows:
Volume = 45 g ÷ 3.0 g/cm³ = 15 cm³
Therefore, the volume of the object is 15 cubic centimeters.
Understanding and applying such volume calculations are crucial in physics, chemistry, and engineering, aiding in the characterization and measurement of physical properties of various substances and objects.
