Density- The proportion of mass to volume of an object. Density determines what floats and what sinks. More dense sinks less dense will float.
The amount of an object does not change the density. Which is more dense 1 gold coin or 1 gold brick? Answer the have the same density, they are both gold. The proportion of mass to volume will remain the same. Density Calculations
The density (d) of a material is its mass (m) divided by its volume (V). Example 1-Solving for Density
Calculate the density of an object that has a mass of 25.0g and the volume is 10.5ml.
d=2.38g/mL Example 2-Solving for mass
Calculate the mass of an object that has a density of 8.92 g/ml and the volume is 5.25 ml. V= d x m V= 8.92 g/ml x 5.25 ml V=46.8g Example 3-Solving for Volume
Calculate the volume of a sphere that has a mass of 21.0g and the density is 12.0g/ml.
vol=1.75mL
