Evaluate: Mass, Volume, and Density

Here's a video from the Evaluate section in the "Mass, Volume, and Density" 5E Lesson. This section aims at reviewing and evaluating newly acquired knowledge: it includes a video which goes...

Density Practice Problems

To see all my Chemistry videos, check out http://socratic.org/chemistry We'll practice solving density example problems. We'll look at how to use the density number like a conversion factor,...

Mass vs. Density

Does one candle float because it's bigger? This video is part of the Flinn Scientific Best Practices for Teaching Chemistry Video Series, a collection of over 125 hours of free professional...

Density, Mass, and Volume.

http://www.itsyourgrade.com presents how to determine an objects density when given it's mass and volume; also including unit conversions.


Just like all matter water has physical properties that can be measured and calculated. To find the mass of water you will need a beaker and a scale. First find the mass of the empty beaker....

How to calculate mass - density question

How to calculate mass knowing density and area. This is a level C GCSE question: "An 8cm solid hexagonal prism has a cross-section area of 15cm squared. The prism is made from wood with a...

Density, volume and mass

Quick notes and demo on density, mass and volume. I also demonstrate how to find the density of two different kinds of objects.

Ideal Gas Law Practice Problems with Density

To see all my Chemistry videos, check out http://socratic.org/chemistry Instead of using the regular ideal gas equation, PV=nRT, we'll use a transformed version (D=PM/RT) in order to solve...
