Density Think back to our definition of matter (anything that has mass and takes up space). What is another word for how much space something takes up? (volume) How can we relate mass and volume (density)

What is Density? Property of matter Physical characteristic of a substance Can be used to identify a substance Ratio of mass to volume for a specific substance

Density Formula Mass Volume Density = Units 1 cm3 = 1mL Liquid: g/mL Solid: g/cm3 Gas: g/L D M V 1 cm3 = 1mL 1 cm3 = 1mL

Properties Of Density Varies with temperature Inversely proportional to temperature Draw D T and D T

Water Water is most dense at 4°C (1.00 g/mL) Water at 100°C is 0.958 g/mL Water at 0°C is 0.999 g/mL Why is water most dense at 4°C, a temp lower than freezing?

Examples What is the density of a substance if the mass is 354g and the volume is 243 mL?

Pure lead has the density of 11. 34 g/mL Pure lead has the density of 11.34 g/mL. What is the mass of a piece of lead that was placed in a graduated cylinder and the water level rose 5.00 mL?

A 34.6g piece of gold was placed in a graduated cylinder containing 25.0 mL. The water rose to 27.4 mL. What is the density of the gold? Is the gold pure if the actual density of gold is 19.3 g/mL?

The density of copper is 8.96 g/mL. What is the volume of 19.2g?
