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
