Here are the essential concepts you must grasp in order to answer the question correctly.
Density
Density is defined as the mass of an object divided by its volume, typically expressed in grams per milliliter (g/mL) for liquids and solids. It is a crucial property that helps identify substances and understand their behavior in different environments. In this context, calculating density involves determining how much mass is contained in a specific volume.

Volume Displacement
Volume displacement is a method used to measure the volume of an irregularly shaped object by observing the change in liquid level when the object is submerged. In this scenario, the initial water level in the graduated cylinder is 12.00 mL, and the final level after adding the gem is 13.45 mL, indicating that the volume of the gem is the difference between these two measurements.

Mass Measurement
Mass measurement refers to determining the amount of matter in an object, typically using a balance. In this question, the mass of the gem is given as 4.50 g, which is essential for calculating density. Accurate mass measurement is vital for ensuring that the density calculation reflects the true properties of the gem.
