Unit 2 is a unit that covers density, scientific notation, and significant figures. Unit 2.1 is on density.
After completing this tutorial you should understand the following:
Be able to describe density in terms of mass and volume
Be able to describe density mathematically
Be able to calculate density mathematically when given mass and volume
Be able to explain why one liquid floats on another
We will also do a lab in the classroom to help you understand the concept.
