Cliff Notes

I. Measuring Density

A. density: mass per unit volume

-in other words, how much stuff there is per unit of space

B. Properties of Objects with Different Densities

1. liquids/objects with lighter densities will float on liquids/objects of heavier densities

C. Formula for Density

1. D = m x V

D = density m = mass V = volume

2. Units of Density

-regular object = g/cm3

-irregular object = g/mL

3. Examples

Ex1 Volume of water = 5 mL, mass of water = 20 g. Density?

4 g/mL

Ex2 Volume of white board eraser = 10 cm3

Mass of eraser = 5 g. Density?

0.5 g/cm3
