What is density? in this video we explain in simple terms what density is, why it is important, how to calculate density in both imperial and metric units as well as worked examples to help you learn and apply your knowledge.

We'll practice solving density example problems. We'll look at how to use the density number like a conversion factor, to solve for mass or volume. Watch this video after the density introduction or before the more complicated video on density exercises that has unit conversion.

How to solve density problems when you have to calculate volume by displacement of water in a graduated cylinder. Density and volume and given, and mass in the unknown.

A demonstration of how to graphically determine density from measurements of mass and volume of several samples of the same material. Includes assigning and labeling axes (0:45), spreading out data throughout graph (1:26), placing points (3:04), estimating a best-fit line (4:25) and calculating its slope (5:44), and titling the graph (7:49).
