Science: Mass, Volume, and Density

Density, the measure of mass per unit volume, can be found by simply dividing the mass of an object by it's volume.
M/V=D

If you HAVE the density and volume and you want to figure out the MASS of an object, take your density and multiply it by your volume.
D x V = M

And if your looking for the VOLUME and you have the mass and density, just divide the mass by the density.

M/D = V

Remember, volume is the amount of SPACE something takes up, mass is a measure for how much matter is in an object and density is a measure of mass per volume. I also like to think of my garbage can after I forget to take out the garbage the previous week - the bin is the same size (volume) but I've been forced to increase the amount of matter (mass) in that same space thus increasing it's DENSITY!

oh, yeah...units we've been using in class:
* the gram(g) is a unit of MASS
* cubic centimeters (cm^3) or milliliters (mL) are units of VOLUME
* and grams per milliliter (g/mL) and grams per cubic centimeter (g/cm^3) is for DESNSITY
