CORNELL NOTES PAGE 77: DENSITY

DensityIt is the mass to volume ratioWhat is mass?

The amount of matter in an objectWhat is volume?

The amount of space an object takes upDensity is the amount of matter an

object has in a given amount of space

Density = Mass ⁄ Volume

IF AN OBJECT HAS A MASS OF 5.854 G AND A VOLUME OF 7.57 CM3.  WHAT IS THE DENSITY OF THE MATERIAL?

First:  Write the correct formula at the top of your page, and list the knowns and the unknowns. D=m/V D = ? M= 5.854 g V = 7.57 cm3

Second: Substitute the known values in the problem D=5.854g/7.57cm3

Third:  Calculate your answer, including units D = 0.77331571994 g/cm3  

Fourth:  Round to the correct number of significant figures  D = 0.773 g/cm3

CORNELL NOTES PAGE 79

When solving for mass, we must take the original formula, and isolate the unknown:

Start with the original formula:d= m/v

Multiply both sides by v:v × d = m/v × v

The "v's" cancel out Rewrite for mass:

m = v x D

When solving for volume, we must take the original formula, and isolate the unknown like so:

1. Write the original formula:

2. Multiply Both sides by V:1. The “v”s cancel out
