Solving Advanced Density Problems with Volume Displacement

The video tutorial explains how to determine the mass of a piece of Iron using a graduated cylinder filled with water. By measuring the water displacement caused by the Iron, the volume is calculated. The density of Iron is then used as a conversion factor to find its mass. The tutorial covers the concepts of volume, density, and the mathematical steps needed to solve the problem, including unit conversion and significant figures.
